wrdmn: If someone is still looking for a solution to the Ground Control start up crash in win 10:
Finally got it working with a patch from moddb, but cannot post the link for some reason (sorry). There are only 2 mods on moddb for gc1 so you should find "Ground Control windows 10 crash fix". It contains a "dinput.dll" which is placed in the game folder. And then it just works.
Also works with the current version of the resolution changer (google "gitlab fkrull gc-resolution-changer", again cannot post link *shrug).
Please note that the resolution changer seems to not work with resolutions > 2048x1536 like mentioned in this thread by XenoRad (Thanks!)
Really happy to be able to play the game again :)
