This is a new installation running on XP Pro SP3

After accepting the Failed message another message appears

Runtime Error

Program .... Program files\Solidworks corp\solidworks(2)\solidworks.exe

Abnormal program termination

I checked for updates to my OS and it is current.

Also, when I installed SW2011 it found but didn't delete or overwrite the older version SW2009 which was left over from when I was telle-commuting with a former employer, so it created secondary SW folders (solidworks(2), etc).

Does the NET Framework error have anything to do with the double folders or should I uninstall everything, SW2009 and SW2011 and star over?
