So I installed Commandos Behind Enemy Lines and tried to play...

DirectX 5 not found - Renamed comandos.exe to commandos.exe

Started the game again...

Shows the Comandos splash Logo and...

"Commandos.exe stopped working"

Tried several compatability options...

- Run as Administrator
- Run in Windows 95
- Run in Windows 98
- Run in Windows Vista
- 16 bits color mode
- Screen resolution 640x480

And nothing always the same error.

I´m runnig on Windows 10 64bits

In the Control Panel (not Settings), go to Programs and Features -> Turn Windows features on and Off. Open the Legacy Components section and tick DirectPlay. Reboot the computer afterwards just to be sure it's properly loaded.

Just to rule it out, try applying the Ultimate Fix for both BEL and BTCoD (originally made for retail and Steam versions), might do the trick: https://docs.google.com/file/d/0B1IQhcL6aChuU3NYS1pzZ2k1eWs/edit

Well I haven't tried that last solution but on a different PC it runs but for some reason I can only play at 800x600 if I try 1024x768 the image gets resized in a very weird way on my 27" Full HD tv... Really weird...

As soon as I can I'll try it out on the other PC and see if it works.
