I dug out an old game of mine having noticed that the Windows 7 Compatibility Centre claims that it is Win 7 64-bit compatible. The game in question is Microsoft Train Simulator v.1.
Yes, it installed in compatibility mode, and it started without any corruption of the initialization screens. It ran very well in actual fact.
Unfortunately, it would not unattended. I could play out any of the tasks included, but turn my back for a few minutes and it would disappear as in close down. There was no fuss, no error message, nothing in Event Viewer, and the Action Centre was completely oblivious to what was happening.
The fix is easy enough. Don’t install in compatibility mode and don’t run it as an administrator..
