Why does the install program for PersonalBrain 5 not launch completely in Windows 7 RC1?
It always gets stuck about six sevenths of the way.
Many Windows 7 (and Vista, I reckon) application setup hangups can be traced back to user permissions. Usually the application fault when the last stages of the setup try to write to protected areas like "Program Files". But sometimes because of the user profile settings not allowing some type of procedure to take place.
I'm actually unsure as to why this happens. After all we are expected to either get a UAC prompt, or a permission denied prompt... or even a crash. But it just hangs sometimes. Clearly something Microsoft needs to work on in future patches.
In any case, there's a few things one can do to ensure proper installation. Or, at the very least, eliminate this possibility from the list of hangup causes:
If while doing any of these procedures you get a prompt telling you this application didn't install properly and asking you if you want it to install under recommended settings, unless you are sure this time it installed properly, accept installing it with the recommended settings.
This clears up the user permissions as being the problem, and instead tells you it's a compatibility issue with Windows 7. The recommended settings are a good option, because your setup will be wrapped around an even better shim than that provided by the Compatibility settings.
