I have an INNO script file for installation and uninstallation. It works fine however, on some machine the uninstallation part causes trouble. Basically, it installs a COM server and registers it in Windows regsitery but it doesn't uninstall the COM server from register. Meanting after installation is over and says that all things are removed still user can see it in Excel.
How should I use REGSVR32 /U /A_FOLDER/MYAPP.DLL ?
