Unzipped into a folder but then it would not find Devil.dll etc so I assume it must be unzipped into Spring\ folder. So I did that.
Start the .exe, it says "Progress: loading map (blabla)"
Finally it is done, I click the "Einzelspieler" tab (single player)
Get this message:

Click yes. It does stuff and seems to finish.
Get message about some missing file. The file is there.

click ok.
This appears:

After clicking okay it does not exit.
click Einzelspieler again, it wants to cache again

Try to close the program, get this message:

and the program does not close
Try clicking [x] a few times, always same error.
Use taskmanager to close it.
Just noticed I also saved a screenshot of this message:

but I do not remember when that appeared.
(the file is also there)
