New Post: MapWindow on x64 systems

I've just checked MapWindow Lite, it uses x86 MapWinGIS (the ocx) but is compiled as AnyCPU, so it should work.
Perhaps the new laptop doesn't have the correct .NET Framework version or not the proper C++ redistributables?
The installer for MapWindow v4.8.8 should check for that.
What happens if you manually register the ocx on the new laptop, perhaps with elevated admin rights?

Could your co-worker try to install MapWindow Lite (https://mapwindow4.codeplex.com/releases/view/542097)?

Thanks,
Paul
