Hello,
Do you use our
predefined support for downgrade?
Can you please send us by email to
support at advancedinstaller dot com the following resources:
1. the .AIP (setup project) file for the old and the new project.
2. a download link for the old and new setup.
3. an
installation log when performing the downgrade process.
Looking forward to hearing from you.
Best regards,
Liviu
