OS - Windows 7 SP1. Program will not install after they upgraded me to Windows 7. The installer starts to run, then disppears - no installation. The compatibility troubleshooter inevitably ends up with "incompatible program". I am dead in the water - I've tried every option I can find, turned off UAC to try to disable compatibility detection, etc. NO luck. I have to get this working, I have a large number of legacy designs that I need to access. I have zero chance of buying the full version of Tina, they will just say it is incompatible and turn me down. HELP!!!!
