we have a version of our accounting system that work on WPF and it used to work fine until we upgraded our client windows from windows XP to Windows 7. Now each time we try to use the system we get the attached error image. it seems that its a compatability problem between the WPF Platform and the window 7 although they are from the same source. ? any idea if thier exists a solution for this ?? error screen shot

I do not use WPF, but a recent Microsoft web page from December 2010 suggests it uses/needs .NET Framework 4. Do you have .NET Framework updated to V4? And if so, does your Accounting System work with .NET Framework V4? Also, the error message above says you are using Windows 7 64-bit (as I do). Perhaps your Accounting System is not 64-bit compliant.

You can download XP Mode for free in Windows 7 64-bit. Perhaps that is a way around it.

I assumed because this is a business issue that you would have been using Windows 7 Pro. So you should consider the anytime upgrade to Pro. You might want to see if this will work if you can get access to a Pro machine. In any event, I recommend Pro for business use. ... Thinkpads_User
