MapWindow v4.8.8 is compiled for the same CPU as the ocx. So not AnyCPU but x86 or x64.
You should try the x86 version of MapWindow since it is newer than the x64 version.
After installation a file called regMapWinGIS.cmd is copied in the destination folder. It is just a text file. You can open it and remove the /s in the regsvr command and run the file again as admin. It should give you a message if the ocx is properly installed or not. If it is not, most likely it has to do with rights or missing (C++) dependencies.
If it is registered and mapwindow.exe still crashes you might have issues with .NET Framework. MWv4 needs .NET Framework v3.5.
Don't you get any error message? How do you know it is crashing?
