I'm trying to uninstall a project wich is developed in Visual Studio and installed using the msi-file from the install project. I can find it in the list of install projects, but when I right click and choose uninstall program the application isn't uninstalled, and I don't get any message. I have no clue what to do so please help.

EDIT: I have tried to run msiexec.exe /X{product code}, but the program stills show up in the Add/remove program dialogue. I have also tried to remove the key, the one under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall, in the register manually and that made it disappear from the add/remove program screen but I still couldn't install a new version.

Previously I would have said to use the following tool:


But I'm not sure how well it works on Windows 7 having last used it on Windows Vista, it should be okay but the usual caveats probably apply!

The solution to my problem was to use to uninstall the program. It seems like there were multiple registry entries that was wrong.

Then enable IIS 6 compatibility to be able to install, don't ask me why since I didn't have it enabled when doing the original install.

Hm.. not the complete solution because I still can't install the new version of the program. – Tomas Jansson Oct 26 '10 at 9:04
