I was able to install and use V17 successfully on Win7 x86 but not Win7 X64. V21 installed on Win7 x86 but crashes on startup. But something baffles me, V21 does not run on Win7 x86. You would think the new version, V21 would run and not the older V17.

Has anyone been able to get V17 or V21 too run on Win7 X64?

I also did a quick test on Win10. The V21 runs flawlessly but V17 won't even install... ???
