I am having the same issue, searched the web it seems common. Im no computer whizz and I can not solve it trying to follow the other ideas (W7 is not as easy to work with when your used to XP)

Same deal Windows 7 64 bit i5 processor etc etc, original software and same error as above, finished by the rollback. grrrr.

Is there a solution without being a computer engineer

Be sure that you have the latest .NET.

Please start an Elevated Command Prompt: How to start an Elevated Command Prompt in Windows 7 and Vista

and copy and paste in the following:

fsutil resource setautoreset true %systemdrive%\

attrib -r -s -h %SystemRoot%\System32\Config\TxR\*
del %SystemRoot%\System32\Config\TxR\*

attrib -r -s -h %SystemRoot%\System32\SMI\Store\Machine\*
del %SystemRoot%\System32\SMI\Store\Machine\*.tm*
del %SystemRoot%\System32\SMI\Store\Machine\*.blf
del %SystemRoot%\System32\SMI\Store\Machine\*.regtrans-ms

and press enter after the final line if necessary.

If you are asked if you are sure, type Y and press enter.


Then I installed msxml 4.0 SP2, but it probably isn't needed as FSX installs this at the end.

This fixed it for me.
