Problem with installing Qt visual studio Add in
taibc last edited by
I tried to install Qt Visual Studio Add in (on Win 7), but it couldn't complete the installation (It doesn't show any message). Then, I used the Task Manager to stop it, and tried to re-install again.
But, I got an error: "A previous installation of Qt Visual Studio Add-in was detected. Please uninstall it before running this installer"
I tried to find it in Control Panel to remove the program, but not found.
Do you know how to fix it ?
Thanks and regards,

welcome to devnet
My expectation is that there are already some changes made in the registry.
My suggestion would be to use "system backup possibility" as it is provided by windows. This allows you to bring the system into a state as prior to your failed attempt to install vsaddin.

I've found a solution for this problem.
I've deleted the following entry from the Windows registry:
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Qt Visual Studio Add-in 1.1.11 - C:_Program Files (x86)_Qt4VSAddin]
Perhaps you will have to correct the key path if you are using a different version.
I arrived to this solution by detecting that the installer was accessing to that section of the registry (I did that with SysInternals Process Monitor), then I exported the registry section to a .reg file and then searched for "Qt" string in that file.
Hope to help someone with this.
