Running 32bit Compiled Program/DLL On 64bit Machine?
May 20, 2011
I have some programs written in VB2010 using functions from a DLL. I have compiled and run these programs on a 32bit XP computer and a 32bit Win7 computer and have had no problems accessing the DLL.I have published an installation of these programs and tried running the install on a 64bit Win7 machine and the installation is performed correctly. It installs the programs and copies the required DLL into the same folder. the problem is that whenever I run the software and try to access the DLL I get errors.
The error says something like:
An unhandled exception has occurred in your application. An attempt was made to load a program with an incorrect format. (Exception from HRESULT:0x8007000B)
If I click past it the software runs and all of the forms are loaded properly, but anytime in the software if I try to access the DLL I get the same error.I am declaring functions in the DLL like this:
Public Declare Function OpenDriver Lib "OP815M.DLL" (ByVal handle_Renamed As Integer) As Integer
I have also tried placing the DLL in the system32 directory and also the sysWOW64 directory and that did not help as well.I do recall that hardware drivers need to be properly signed and pass the Microsoft Logo testing. Must I get the DLLs I am using properly signed?
Edit: Also it might be fair to mention that I have used the DLL with another program written in C, which would run in the DOS command line in Windows and it correctly accesses the DLL on a 64bit machine, but just when run from the DOS command line in windows.
I developed a Visual Basic program in VS2005 that uses SQL2005 on a 32bit system, which runs perfectly on 32bit systems using Click Once deployment, but whenever I try to load or run same program on any 64bit system, it does not load or run. What do I need to do to make the program run on 64bit systems.
i've finally finished my A2 project by building a program for a real life solution. This program works on the school computers which are 32bit XP but when i try to run it on a Windows 7 64bit system, i can't get it to work after trying various things.
error:The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine.
Basically i want to run a program that is created in vb2008 with its compiler properties set to AnyCPUThe programmer has a 32bit os, so he has not recognized that his referenced assemblies are not compatible with 64bit OS and therefore throw system.badimageformatexception on 64bit OS (such as mine; im running windows 7)
now it is my understanding that all 32bit applications can be run on 64bit windows because the WOW64 emulator can run them (just like programs that get installed in the program files x86 directory)so the problem here is that my OS cant recognize that this program must be run in 32bit since that programmer foolishly set the compile options to anycpu i can not contact the programmer and therefore asking him to recompile is not a possible solution.So, how do i run this program as 32 bit on my 64bit OS? how can i manually set 32-bit compatibility? it is not available in compatibility options.I tried running in compatibility mode for windows xp sp2 i tried putting the software in program files x86 folder.
I am moving to a Windows 7 64-bit development machine. Talk about causing problems. I've Googled, but can't seem to find much to help my specific needs. I'm hitting maximum errors in my IDE error list, so I won't start listing them. I've tried targetting both x86 and x64, but I still get errors out the wazzu. Is there a good starting point for me to learn how to do this? or should I just start going through the errors and trying to correct them one by one?
Here's the situation - I have a vb.net exe compiled for X86 machines using 2 dll's... Because one of the dll's was only provided in 32 bit, and I didn't want to have to deal with 32/64 versions, I forced 32 bit in compile options and everything was fine. Now I have a 64 bit workstation that is throwing an error about the sqlite.dll (error #1 below).
after reading around I am starting to understand a lot of people are having this issue. I tried replacing the dll on the client machine with the 64 bit version of sqlite and that didn't work (error #2). I read somewhere that the 64 bit version requires VC 2010 redistro, but that didn't work. I can't compile this app as a 64 bit because of the other dll is 32 bit.
I'm using the following code to iterate through and find windows containing specific strings in their title bars. I have two projects containing this identical information, yet for some reason - it works when targeted to x64, but FindWindowLike returns 0 always on x86. I need this to run in x86.I am developing this on Windows 7 x64, but it needs to run on my machine as well as XPx32. What I can't fathom is why it compiles/runs on x64 but not x32 (considering I'm targetting user*32*.dll)
I had a vb6 applications which using following dll files 1. shell32.dll 2. user32.dll 3. comdlg32.dll 4. apigid32.dll. It is working fine on vista 32bit OS . Now i am trying to run my application on Vista 64bit OS.
Is it working fine on vista 64bit OS with out any changing in vb6 code?Is there any problem with this above mentioned dlls on Vista 64bit OS?
Something that is bugging me which My application is targeted for 32 bit machines but I'm not sure which .NET installation package to use with my deployment: 32, 64 or the package with both.I currently bundle the .NET 32 bit installation with my installer and that works fine. I don't have a 64 bit machine to test with, so my question is what version of the framework will my application need on a 64 bit machine?
Ok server is Windows Server 2008 R2. I've already installed other 32 bit applications. I had my own application compiled as ANY CPU, I just copied the folder containing my executable and DLL files to the server. Doing it this way is fine on Windows 2003 Server and other 32 bit operating systems. I registered the DLL files by using regsvr32. When I ran the file, it would come up with an invalid exception error. I compiled it as x86 and tried it again and it crashed immediately without any errors.
So I have VS 2005, application compiled as x86 - what do I do to get it running in Windows Server 2008 R2?Also as a side line, I didn't know that the server was 64bit to start with so I installed 32bit MySQL - should I remove and install 64bit?
Our application is one EXE and multiple DLL's. Right now, we are compiling all of them for x86 so we are forcing 32bit because the running size of the application is a lot smaller (memory usage).If we compile the EXE as x86 and the DLL's as anyCPU, on a 64bit machine will the DLL's be 32bit or 64bit?
the reason for my question is if i can compile the DLL's for anyCPU and then have two EXE's, one for 32bit and one for 64bit, then i have only one duplicate program for the 32 or 64 bit change, and if a user wants to run full 64bit they only need to run the 64bit EXE and everything is fine. But if a user is on a 64bit machine but wants to run in 32bit mode, they would run the 32bit EXE.Let me know if this is true. i can't test this as i develop on a 32bit XP machine.
I have compiled my app (Just standard windows controld, no third party) on my 64bit system to run on a 32Bit XP system. In have tried all the different settings (x86, x32, All) The error i get is: MyApp.exe has encountered a problem and needs to close. Sorry for the inconvenience. This is my first post here, I hope i havent managed to break any rules
We have a winforms appliction that has to talk to an AS400. To do this we imported the IBM.Data.DB2.iSeries classes in the Winforms application and have IBM System I Access for Windows on our machines. It must have the System I Access or it will not talk to the AS/400. Everything works fine on my 64bit development machine. It also works fine on the client's 64bit machine. However when we attempt to install it on a 32bit machine we get a Bad Image format exception. We tried making just an x86 installer instead of any cpu but that did not work (same bad image exception).
I am trying to execute DiskShadow on Server 2008 R2 via Process.Start
[code]...
Now, what's happening is that the Diskshadow script fails with a "com call "(*vssobject)->initializeforbackup" failed." If I then open a command prompt/powershell prompt as administrator and execute "Diskshadow -s diskshadow.txt" manually it works just fine.
If, however, I try c:windowssyswow64Diskshadow -s diskshadow.txt I get the exact same error as when I try to run it via Process.StartSo, there seems to be some 32bit weirdness going on here when I try to run Diskshadow via Process.Start (Even though I am forcing it to use the copy in C:windowssystem32
i have my app code which programed on 32 bit now when i copy it to 64 bit and try to open the project i get this error Quote:Type library importer encountered a property getter 'sessionPlaylistCount' on type 'WMPLib.IWMPNowPlayingHelperDispatch' without a valid return type. The importer will attempt to import this property as a method instead.TlbImp
I would like these to have their separate "Bin" folders too if possible at all (I tried using "Probing" but I guess that's not allowed for web apps and defaults to "Bin" folder). If not that then definitely some ability for these to work together under one app/virtual directory because I'm not allowed to create another at any cost :(
I'm making a program from witch one could run an application with different credentials.I can compile the program successfully, but when I press the button to run the program I get the following error: Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.The system cannot find the specified file.The code behind the button is as follows:
Dim myProcess As System.Diagnostics.Process = New System.Diagnostics.Process() myProcess.StartInfo.FileName = "c: un.bat /user:kreathyr c:getlogin.exe" myProcess.Start()
Getlogin.exe does nothing but show the logged in username and run.bat utilizes the runas command.
I am been working on an a small app that has a Forms.Webbrowser control that navigates to a Adobe Flash program. I have developed the app on Vista 32bit platform and have had no problems. I have sent the app to a couple of people to test out and one is using Vista 64bit and is running into a problem. I know the webbrowser control just uses the underlying base framework of IE. The problem on the 64 bit machine is when the site is navigated to it says that it needs to have Flash installed. When the user goes to Adobe's site it says they need to use a 32bit browser.
As stated on Adobe site here:[URL] the Flash player need to be in a 32 bit browser. What options do I have to be able fix this problem? Is there another control that I can use that would be the same in a 32bit platform and 64bit platform? Besides navigating to the Flash program, the browser also goes to standard web pages.
coming from VB6 I've been using the windows API for many years. Now I'd lke to do the same on .NetMy question is, what would happen if I build for 'AnyCPU' and the application calls Kernel32 while running on a 64bit machine ?
I'm buying a new computer this week and the one I want has Windows 7 Home Edition 64 bit. I program in VB.NET using VS2008. If I write a program and compile on this 64 bit windows, will it run in 32 bit? I did some reading and from what I understand is if it is not using any specific 64 bit drivers I should be good. I'm not doing anything fancy that I know of as far as drivers. I just wanted to see what everyone's past experience has been.
I wonder if/how to use a 32 bit DLL on a 64 bit machine. The situation is like follows:Autocad Inventor(64 bit program) can launch plugin DLL's. The plugin DLL in this case is programmed with VB.NET 2008 Express edition. As far as I know, I can only choose "Any CPU" when building the DLL with the Express edition. This DLL makes uses of a COM object called Isah IERPlink, a piece of software that is used with a 32 bit package. So in my bin directory this DLL will be added "interop.IERPlink.dll". I guess this DLL is specified for 32 bit CPU's, but I'm not sure.
I have created an application using VB.NET in VS2008. When I run the app in the IDE on my development machine it works fine. It also works fine when I build it and run it as an exe on any machine that also has Visual Studio installed (at least 2005 and 2008 anyway) However, when I try to run the compiled executable on any machine without Visual Studio it throws up an error "[program name] has encountered a problem and will close..."
I'm using Visual Studio 2010 Express running on Windows 7 64-bit. I get the same error as detailled in this link [URL] .I need to work with some data to develop the system. I think I can only do this by changing the Copy to Output Directory file property to "Copy if newer" to prevent the debugger from losing it.However this causes TableAdapter.Fill to exit from the sub immediately after executing leaving behind the other code in the form "Add_Load" routine.
I have windows7 home premium 64bit edittion, I use VB6 and VS2008. I recently install Win7 SP1 in my machine but after installing the SP1 my old VB6 application is working fine in my pc but compiled exe files are not working in other windows XP machine, then I uninstall WIndows7 Sp1 from my PC and again compile the old vb6 application, now i notice that this exe is working file in all other pc. is there any way to use win7 sp1 with vb6 ??
I have an application that will not load unless my local SQL Server is running on an Vista Home Premium machine. This started after a .Net 1 to .Net 4 conversion. I am using a sub main sub that is not being called (msgbox is not fired when entering the app), however, I see the app through taskmgr with increasing memory usage, but then the app is removed from the list. By design, if the program cannot locate a SQL Server a form pops up with a connection box to locate the SQL Server for the app. How it determines if it has a valid connection is the program looks for a connection string in the registry, then attempts to connect to it, however, none of this code executes because of the failure to enter into the sub main.The two machines I have tried the 32 bit app on
XP Pro: Failed / Using SQL Server 2008 Express
Windows 2003 Server: Works / Using SQL Server 2008 Developer
Both machines have .Net 4 Client Profile with Extended?
After compiling the project it works fine on windows 7 32bit and 64 bit but will not work on server 2003 or xp clients have not checked vista yet, i have verified that .net 4 is installed and i can tell you that i do not get an error message when installing apart from the icon that i have given the project does not appear and is a blank icon on the desktop. When i try to run the program it will try to start i see the service in the task manager and after a while it will error out and crash. I can see the memory usage go from 20,000K to 70.000k.
