Transport Tycoon / OpenTTD is my favorite game of all time, and I wanted to play it on Steam. I kept getting "file not writable" error. I tracked it down to the Windows security system blocking it. To unblock:

  1. Start →
  2. Settings →
  3. Update & Security →
  4. Windows security →
  5. Open Windows Security →
  6. Virus & threat protection →
  7. Manage settings →
  8. Controlled folder access →
  9. Manage Controlled folder access →
  10. Allow an app through Controlled folder access →
  11. Add an allowed app →
  12. openttd.exe

I am not a fan of making exceptions like this but I didn't find anything else that worked. If you have an alternate method of solving the permissions error, please let me know.

The first thing I want to try is the FIRS mod!
