Hi,
Since you overwritten an older installation of Advanced Installer most likely it was corrupted. Also, I'm not sure if uninstalling and reinstalling it completely removed the corrupted data. Please use the Windows Installer Cleanup utility to remove
ALL versions of Advanced Installer which are present on your machine:

After this, make sure that the folders which contained the Advanced Installer installation doesn't exist. Finally, perform a
clean installation of Advanced Installer.
Regards,
