TurboTax 2011: Windows XP Mode to the rescue but problem persists under Windows 7

I had to resort to Windows XP Mode to be able to run TurboTax 2011 after one last attempt (one of many) to reinstall the program. Apparently, disabling the antivirus program, and modifying the Firewall inbound and outbound rules before installing did not help this time either. Same old story: I get a terse "TurboTax 2011 Is Installed" message with a "Done" button to click on. Then, the same frustration (see previous post) and the program does not start and does not even say whatever is wrong. Will I, or any of my readers, ever know what happened?On the other hand, Windows XP mode, which I like a lot, is not intended to run "new" software. "New" software should run well under Windows 7. No excuses. On the other hand, it is clear that Intuit, the company behind TurboTax, is aware of this problem, as indicated in their user forum here,  and also here, where other folks have complained too. It seems that this "old" problem apparently has not been taken care of. That is just unacceptable!
