XML Notepad 2007 has stopped working - Windows is looking for a solution to the problem

I get a dialog box with this message when I try to use XML Notepad. The dialog disappears without any solution suggestions.

I am using Windows 8 & .NET 4.5. I have had no other issues with Windows 8, so I am reluctant to be suspicious of it. Does anyone have any suggestions as to what might be causing it or how I might diagnose what might be causing it?

After working on this for about 7 hours, I figure it out. Whew, it was a lot of work and hair pulling, but XML Notepad has been a trusted friend for years and I was not about to leave her behind on the battlefield. Aw shucks, it was the least that I could do, she has been good to me and giving me her all for years and it made me happy to figure out what was ailing her. It appears that the later .NET Frameworks are not compatible. During the experience, I also found that there was a problem with XamlPadX, it fixed her too. Also, during the experience, I have really made intimate friends with Windows 8 and just beginning to love her too. I am such an easy boy. Maybe actually a real a first class wh!@# for this stuff. This is Friday night and I should be prowling around somewhere putting myself to good use! LOL.

Doing this fixed her for me:
Install .NET Framework 2.0 SP2 and an update for the .NET Framework 3.5 Service Pack 1.

Version 2.6 should resolve this, I upgraded good 'ol XML Notepad to .NET 4.0. That should let her live a little longer :-)
