Can Uninstall Functionality Be Modified To Catch Other Instances Of Application / Also Uninstall Them?
Jun 23, 2011
Have a VB.net application that installs initially from CD and then when the user gets into the internet the application updates. In order to better support problems with this application is has been suggested in the past to uninstall it and do a fresh re-install. However, in investigation it was determined that the uninstall does not consider all installed objects and does not uninstall the CD install.Can the uninstall functionality be modified to catch the other instances of this application and also uninstall them?
I am looking for a way to uninstall an application installed using the MSI Installer.I believe there should be a way out to directly call the Uninstall module specifically for a particular application using VB.Net.How can I achieve this using VB.Net? I am using VB.Net 2005.
I'm looking for any references on the best way to perform an unattended uninstall of a product using VB.NET. The product was installed using Windows Installer and the product name is Dell Kace Agent. I would like to perform the uninstall within the VB.NET code.Here's a VBScript that uninstalls a product using WMIC. This could be converted to VB.NET fairly easily, but is there a better way to perform a uninstall within VB.NET code than querying WMIC? I would rather not use WMIC to perform the uninstall maybe get the uninstall string from the registry?
Since installing Windows 7 on one of my test machines my automated uninstaller can not find the uninstall string. My script works on XP just fine. I noticed that the uninstall information is in a different location for Windows 7. it is in Wow6432NodeMicrosoft... is there a constant I can use that will allow my script find the correct uninstall location on both Windows 7 and Windows XP?
My trial version of VS9 professional just expired and wanted to uninstall it, however upon loading, it goes into debug mode and displays the message;an unhandled win32 exception occurred in setup.exe [3816]If I do go into debug mode, then it loads VS but since my version is already expired, I can't do anything but close it...I can't repair it since I dont have the original installation files (its VS9 professional ENU, and microsoft doesnt have it up for downloads anymore.. but here is a SS of the other programes installed which are related to VS9.[URL]..
I've taken MS 4994A (Intro to VB.net), and am studying for 4995A (Advanced Intro to VB.net)Previous experience with VB6 and C++ tells me that the way to do it would be to create a program that will accept a list of computer names and check the registry one-by-one (I'm open to suggestions, though, of course). If it finds the program we're wanting to remove, it will remove it, then automagically install .net 2.0 and the .net version of the programs that were just removed.
I have a project that creates and installs a window service. I want to uninstall it because it is running both on my PC and on another. I want to leave it on the other. So when I open VS with the project, I right-click on the servicesetup and choose uninstall and it says "This action is only valid for products that are currently installed." It is listed in control panel Services, so isn't it installed?
I have an application that contains an MDB. This application has a feature that will allow the user to update the database to a newer version that is on a thumb drive.The database ispart of the application and is not user-updatable, so it seems as though it should live in the Program Files directory with all the other data files (xml, etc.)However, somehow it found its way into the Virtualstore.Now when I go through my process to update the database via the application when I try to run the application is is re-routed to the old mdb in the virtualstore.
But much worse than that, I found out that the virtualstore for the application survives a reinstall Now to my mind this is a huge bug because one would expect when one uninstalls and re-install an application that would have created a "clean slate" and everything would work correctly. But here I have an instance where the user thinks she has installed a fresh copy of the application but in fact is getting corrupted by old junk in the virtual store from a previous install.
I'm trying to read keys in the HKLM Uninstall section in my attempt to do a software inventory. I tried the WMI, it works but it doesn't show everything. I decided to just read each of the sub keys in the Uninstall section, but it doesn't show everything.
The code works, but it's just not showing some items.
Dim UninstallKey, SubKey As RegistryKey Dim SubUninstallKeyNames() As String UninstallKey = RegistryKey.OpenRemoteBaseKey(RegistryHive.LocalMachine, "\" &
Ive created a shell context menu dll using the great example at [url]...
This dll can be included in a vb.net setup project and installs ok but upon uninstall Windows prompts the user to close explorer.exe for the uninstall to complete. If the user clicks ok then the windows GUI is lost and the user either needs to reboot or know how to run task manager and startup another instance of explorer.exe to get their desktop back.
Does anyone know how to go about uninstalling a context menu dll which is currently in use by explorer without ending the explorer.exe process.
I created a myapp setup project and set "RemovePreviousVersions = true". I have to uninstall previous myapp first and then install new one. Is there any any way to create a setup msi file to uninstall and install at the same step?
(I found no server 2003 forums so i posted here) I have recently been tasked with moving legacy applications (written in VB 6) that have to be migrated from windows server 2K to windows 2003. My superiors tell me that we MUST use MDAC 2.7 because the VB 6 applications are very old and use office 97 (no chance for upgrade because they will break - they will be supplanted by .net applications) Also, if these legacy apps use 2.8 they will break as well.
I know that Windows Server 2003 automatically comes with MDAC 2.8 and there is no way to uninstall it (is there?). But is it possible to install MDAC 2.7 (parallel to 2.8) and force our applications to use the 2.7 version? Or do we have to stick with windows 2k if we HAVE to MDAC 2.7?
I don't know what's got into them but they decided to purchase vs2010 pro licenses in my company. Anyway i gave it a quick look and since i don't need to have it installed right now (service pack 1 first, Microsoft anti-bug law) i uninstalled it. The problem i see is that it leaves leftovers everywhere.C++ redist, ado components, sql r2 components etc. These will not be deleted if i just remove vs2010 but will be installed if i install vs2010 full.Anyway i ended up removing them one by one and it took about 30-45 minutes. So has anyone have done a removal? Is this the case? I cannot remove most of the components with one big uninstall?
I want to excute the uninstall command with VB.NET, but want to wait until the uninstall process finished like Control Panel, the Shell command seem not realize it.[code]...
I am working visual basic express, when I installed it came with a bunch of programs which are:
Microsoft SQL server2005 Microsoft SQL server2008 Microsoft SQL server Compact Microsoft SQL Server System Microsoft visual c++ redistributable 2005 Microsoft visual c++ redistributable 2008 Microsoft visual c++ redistributable 2008 Microsoft visual c++ redistributable 2008 visual studio 2010 ADO.net entity framework tools MSXML 4.0 SP2 MSXML 4.0 SP2
Since then my PC became heavy and slow, I want to some of the programs but I am afraid that vb express won't function properly. Can someone tell me which program can be removed without problems?
I use Project Setting in visual studio 2008 and everything works correctly and save my information when the application is closed. However the information it lost when the application is Uninstalled. The information is not available with my new install.how to keep Project Settings through uninstall and installs!
I'm trying to add a printer as part of my install and then remove that printer as part of the uninstall, and I'm not having much luck. I can add the printer using a shell command and the "printUI.dll" but when I try to use the addprinter() from the windows API, nothing happens. When I try to delete a test printer with the deleteprinter() function, it executes fine... but doesn't actually remove the printer. Everything I've been able to find on it seems to indicate that my code is right, but obviously I'm missing something because its not working.
VB Module Module1 Public Declare Auto Function OpenPrinter Lib "winspool.drv" _ (ByVal pPrinterName As String, _ ByRef phPrinter As IntPtr, _ ByVal pDefault As PrinterDefaults) As Int32 [Code] .....
I'm kind of shooting in the dark here - searches don't seem to be productive on this. I want to create a .NET program to monitor the install and uninstall of fonts. If something is installed or uninstalled, I want to run a program to do something.
I thought maybe a Windows Service, but haven't gotten very far with figuring out how to monitor fonts. Is this the right way and if so, what am I overlooking? If not, is there a different way to do this?
I have program that on first run will run after installed will setup a server connection. The next times the program is run it will not execute this code to setup the server as it was done in the first run.
I can't use clickOnce IsFirstRun as the customer doesn't want that used for installation.I am using MSI to create the setup. I right click setup / view / Registry. I create a key value, example "HKEY_CURRENT_USERSoftwareReality", "App", "Installed"I set the property AlwaysCreate = false, and DeleteAtUninstall = true.
My big question I don't want to create the key value when the application is first installed. Only delete it when uninstalled.My code for checking for the key value:
Code:If (My.Computer.Registry.GetValue("HKEY_CURRENT_USERSoftwareReality", "App", Nothing) <> "Installed") Then 'The program is running for the first time so create key value My.Computer.Registry.SetValue("HKEY_CURRENT_USERSoftwareRealitySolutions", "CodeRed", "Installed") 'Setup server for the fist time Else 'The key exists so go no need to setup the server'Do something else End If
The key value deletes on the uninstalled - which is what i want it to do. However, it always creates the key value when installed. i don't want it to do this. It should only create the key value in the code.Can any tell me, when setting up the registry in the setup project, is there a way to stop it from creating the key value when the program is installed.
registry key and check the displayname & displayversion registry value for all the sub keys under the uninstall key then compare the displayname & displayversion value with a if statement.
For example if one of the the displayname = "Adobe Flash Player 10 ActiveX" & displayversion = "10.1.82.76" then textbox.text = "Your adobe flash is up to date"
This is the code I been using to check a specific registry value to see if quicktime 7.67.75.0 is installed i figured it would be best to enumerate the subkeys and check the displayname & displayversion because im checking like 6 programs to see if the version is current.
Dim quicktime As String quicktime = My.Computer.Registry.GetValue _ ("HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionUninstall{EB900AF8-CC61-4E15-871B-98D1EA3E8025}", "DisplayVersion", Nothing)
