MTA:SA launcher code
MTA:SA error CL42
Windows is in Safe Mode, and MTA cannot run there.
How to fix it
Restart the computer normally
Restart so Windows starts in normal mode, then run MTA again.
Source: MTA help
Turn off Safe boot
Only if the Safe Mode message comes back after a normal restart.
Press the Windows key and R together, type msconfig and press Enter. In System Configuration open the Boot tab, remove the tick from Safe boot for your Windows, press OK and restart.

Still the same

These are the steps of the guide MTA says Windows is in Safe Mode.
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.
About this code
CL codes come from MTA's launcher, before the game starts: installing an update, finding GTA, loading MTA's own files or starting gta_sa.exe. MTA's own documentation gives CL42 as Windows Safe Mode.
