Hello,
Do you have multiple packages of the same setup installed on the same machine? If so, this could happen because of shared components.
Please take a look at the
Why files are left behind after package uninstall? FAQ article.
If that does not help, could you kindly email the following resources to
support at advancedinstaller dot com?
1. the .AIP (setup project) file
2. an
uninstallation log
3, a download link for your setup package
Best regards,
Liviu
