I want my program to be able to edit a values within a registry key that resides in 'HKEY_LOCAL_MACHINE'
My.Computer.Registry.SetValue("HKEY_LOCAL_MACHINESOFTWAREXYZ", "MyValue", "MyData")
The above works fine in Windows XP, but throws an UnauthorizedAccessException in Vista.
screwed up User Access Control, some functionality does not inherit the accounts true privileges. I built a Command Prompt application and ran it from an Admin account, but I kept getting access denied when I ran it. The only work around I can find for now to shut the dam thing off in control panel.

I tried running this application as administrator, even though I am on an admin account. I even disabled UAC. Nothing seems to work. I do not want to just skip the file, I want to read it.How does a antivirus program scan every file on your computer for errors? How do it read the file if Vista prevents it?

As I said before, this had been working for several days, up until now.
I've been doing some more experiments and have summarized the query as below: I've created the simplest application. A project with a plain form, which writes text file within its application directory. Simple as that.Supposing this was my application which I want to distribute on the world web. I've created a basic installer for this using NSIS installer. The Installer installs my application in a folder created inside Program Files. The OS is Windows7 and UAC is enabled.Now I know many people have been facing difficulties in accessing files inside the Program Files folder. My app is simply creating a plain text file, nothing more, and within its own application directory. It is giving Access Denied error. But if I right-click on the EXE and run it as Administrator, then it works ok.The only solution thats available is not to write in the application folder, and write text file in some other folder which is not protected. My question is that other programs that are installed on my system are also doing it. I have a temperature monitoring software called SpeedFan on my system, it creates log files within its app directory. All other softwares create log files within their app directories, why cant I?I just have to make a small log file for my application and Win7+UAC is not letting me do it. I don't want to write the small file in any other folder. How are the other softwares accomplishing this ?

but this code not working on windows vista, i can use it on windows xp, i think problem is user permissions but i have to delete or create file via my application how can resolve this problem.
I'm running Windows Vista with admin privilege and UAC is disabled but still unable to write to windows registry!
My.Computer.Registry.SetValue _
("HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun", _
"Test", "C:Test.exe", Microsoft.Win32.RegistryValueKind.String)
I'm getting error "Unauthorized Access Exception was unhandled."
"Access to the registry key 'HKEY_LOCAL_MACHINE....' is denied."
I've googled the net and found that registry permission elevation is required for admin tasks, Is there away to take registry key ownership through VB.Net code??
I want to replace/delete imageres.dll in system32 golder in vista/7 from vb.net Note : that i have taken ownership of file with cmd in windows 7. And also note when i delete the file from windows explorer it gets deleted successfully but when i do it with vb.net it failes

I am having a windows application. That downloads files from server and write into the local directory. It works fine. When we try the same appliication in Windows 7. IT shows an error Access to the path denied (While writing to the local directory).
View 1 RepliesOk I know this question has been asked to death but I still have not seen a good answer. I have created an application in VS2010 using VB.NET. In my application I have an error log that is an XML file located in the Public gstLocalErrorLogLocation As String = Application.StartupPath & "ErrorLog"that gets written to in the event of an error so I can trouble shoot application easier. My application also downloads files from our FTP site and puts the files in Public gstLocalDownloadLocation As String = Application.StartupPath & "download"So I have files that get read and written to as well and created and deleted all in the Application.StartupPath which is either "c:Program Files(Application Directory)(Some Directory)(Some File)" or "c:Program Files (x86)(Application Directory)(Some Directory)(Some File)" depending on 32bit or 64bit Windows 7.
After creating the setup I install it on my test machine that have both Windows 7 32bit and 64bit.Everything in the application works great till I have to write to, delete or creat a file in those directories above. I know it is an access issue and the UAC. This will get installed on numerous systems so the options I have seen to change file or folder permission on the computers manually is not an option.What has to happen is after I install the application it just works like when you install it on XP. Some post have suggested that you us a user with administrator privilages or group which is all fine and dandy but the user I have used to test the application has all of that.
So what I am asking is how do you create an application with VS2010 in VB.NET that after creating a setup package and installing on Windows 7 will just work with out "Access to the path c:Program Files(Application Directory)(Some Directory)(Some File) is denied." If I have to install this on 100 Windows 7 computers it has to be a concreate no manually doing anything just install and work like when we installed on XP.
I'm just testing my application to ensure all exceptions are handled gracefully, but I'm having problems with one particular error.
The code looks like this:
Code:
Try
fw = New StreamWriter(GlobalFileName, False) 'Open for overwriting
{stuff}
[Code]....
This code seems to catch errors such as the file being used by another process or whatever, but in the case of insufficient permissions to the directory (ie. 'read only') the code breaks with the error:
Unhandled exception has occurred in your application... Access to the path '...' is denied.
It is definately the "new streamwriter" line that is crashing it, but why isn't this particular error handled by the "catch exception"?
My application creates a file by writing to System.AppDomain.CurrentDomain.BaseDirectory() & "data/" & filename...Now this works fine usually, but I just added a setup utility to the app, so now it installs to the program files directory. It installs correctly and creates the data folder, however when it tries to write the file it gets an exception "unauthorized access".
View 3 RepliesI have an old app, a VB5 front end with access 97 databases all works Ok using the ...program files... folders in XP but I now have a user on Vista and we have problems opening up, and I am braced for problems saving and closing down, if we ever get there.
I sent him a c# applet which found the users folder using string Dpath = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);
I have moved the data and all settings files to a folder C:Users[Username]AppDataLocal[My app Name][My app data Path]
The start up routine checks a settings file uses the path in the settings to re-attach the front end database to a backend database, test to see if the database uses replication and set the default data path for the rest of the app. we are failing somewhere in here I am sure. I have checked and there are no updateable files in program files
Have I got the wrong path or is there something else I should be looking for?
I have an vs2008 version of the app which is using a similar location but a SQL server database- no problems

View 1 RepliesProblem 1: I am running into a problem with my program that when UAC is active on Vistaaccess to C: and Program Files is not allowed. My program writes text files as a user types. Is there a safe place to write files to that may be some sort of standard instead of throwing files all over the place? Like maybe somewhere in the user's default folder's or something?
