Description:
Certain AIP files fail to load in the newer version of Advanced Installer.
Reason:
An ancient bug concerning the case sensitivity of file names was discovered and fixed in AdvInst 3.5. Unfortunatelly, some older projects, already broken because of the bug, can't be loaded by the fixed code.
Solution:
Send us the (zipped) AIP file(s) to support at advancedinstaller dot com and we will fix it for you.
Regards,
Cata
