I distribyte my application as a single .exe file created by
ISX_LE .

However, if user deletes manually the directory where my application is
installed, Windows starts prompting for a .msi file forever.

I tried to fix this by deleting the following key from registry:

HKEY_CLASSES_ROOT\Installer\Products\D4630248E9E66D11E8F400008E6D868E

After deleting this key, my application can no longer be removed from Contrl Panel/Add/Remove programs.

Is is possible to disable auto-repairing feature so that I can uninstall my application ?
