André,
Unfortunately, my demo really was too quick-n-dirty <g>. Sorry !!!
Please re-dowonload:
http://www.lindersoft.com/projects/SmartRollback.zip
See Lines 39+40 in the "UpdateSetup.sb8" project:
! Backup Add/Remove Panel data
Set Installer Flag $SB_BACKUPADDREMOVEPANEL$ to "1"
This will backup the required registry items for updates.
Does this help?
