I have the same problem. This problem I have since update to version AI 21.8.1
I will send the AIP file to support at advancedinstaller dot com.
I hope for your help.

I have nearly the same question. The Comodo Extended Validation Code Signing certificate I will buy for better performance of my Setup.exe without Microsoft SmartScreen during start of the Setup.exe in the costumer computer. Is this USB stick certificate usable in Advanced Installer Professional ...
I have done also a mystake by choice Entreprise for test after my test phase is over. Now I would go back to my bought Professional Version of Advanced Installer. Would you help me to get it back again?
