MTA:SA fix
CL22: MTA could not start GTA:SA
Check that GTA opens on its own first. Do that before you change any permissions.
Could not start GTA:SA
Codes on this page: CL22
Steps
Restart, then open GTA on its own
Restart the PC, then start GTA single player from the GTA installation that MTA is set to use. If GTA itself will not open, use the guide for GTA failing to open, or the guide for a missing GTA file, first.

Try Run as administrator once
Only if the Windows error shown with the CL22 message clearly says access is denied, and this is your own PC.
Start the trusted official MTA launcher once with Run as administrator.
Careful: Do not set every game to always run as administrator.

If your antivirus blocked the file
Only if your antivirus or security program says it blocked the official program file named in the error.
Follow the instructions of the antivirus maker for a false positive (a false alarm), or for an exception for that one file only. If there is no such notice, leave your protection as it is and give MTA support the Windows error number.
Careful: Do not allow a file you do not know, and do not turn off your antivirus.
Still not fixed? Copy the whole message, not only the code, and check your log in the Fix tool. It is read on your own computer.
