[Setup]: UninstallFilesDir

Default value:

{app}
Description:

Specifies the directory where the "unins*.*" files for the uninstaller are stored.

Note: You should not assign a different value here on a new version of an application, or else Setup won't find the uninstall logs from the previous versions and therefore won't be able to append to them.

Example:
UninstallFilesDir={app}\uninst
