Remove "_is1" suffix from Inno Setup AppId

Martin Delille

When specifying the AppId parameter to an Inno Setup script, a _is1 suffix is automatically added.

I realized that looking at the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall

Is it possible to disable this suffix?

Martin Prikryl

It cannot be removed. It's hardcoded.

See how SubkeyName variable is initialized in RegisterUninstallInfo function of Projects/Install.pas:

SubkeyName := NEWREGSTR_PATH_UNINSTALL + '\' + UninstallRegKeyBaseName + '_is1';
