CL02: MTA cannot copy update files
Close MTA and GTA, then try the update again. A program that is still open can keep an update file locked.
There was a problem copying files
Codes on this page: CL02
Steps
Close MTA and GTA
Close every MTA and GTA that is running before you try the update again.

Restart Windows before you try again
If copying still fails, save your work and restart Windows. Run the installer before you open the game again.

Reinstall MTA with a fresh, complete installer
If the update still cannot finish, download the current installer from the official MTA site and reinstall MTA. If the error comes back, note the file name it shows and the Windows error.
