I was running UFT ver2 and transferred *sqz files no problem from machine to machine. Then upgraded to UFT UK version 2.9, upgrade went ok. Loaded backup files originally done on ver 2.0 into new version no problem. Both UFT ver 2.0 and Ver 2.9 were loaded into same directory selecting the upgrade option on install of ver 2.9. However if you installed your version 2.0 and ver 2.9 into different drives or directories your back up will load into the original version 2.O directory that it was backed up from. You need only drag the library and project files to the new UFT directory to get everything to work ok. Incidentally I installed version 2.9 into a clean machine, and tried to restore my original backups ver 2.0. The back up proceeded ok but halted when file v_phbook.dbf couldn't be found, I eventually found it in the UFT/Images directory. This solved the problems now everything seems to be ok. There are quite a few other bugs in UFT ver 2.9 so keep a check on the website.
