Error 1722


I have created a basic MSI Package.
I installaed it on Windows 7, it installed successfully but when I am going to un-install it, it is giving an error "Error 1722: There is a problem with this Windows Installer Package. A program run as a part of the setup did not finish as expected. Contact your support personnel or package vendor"

Please provide me any suggestions for how to fix this problem and how to uninstall the application.

Thanks in advance.

Hi Rakesh,

Check to see if your files got uninstalled already. It could be an issue with uninstalling and installing on the same machine multiple times. This can cause a dirty machine. Try manually deleting the uninstall string. Once removed, run your installation again and it should install like normal. Then check if you are able to uninstall again.
