After I updated MTA to version 1.6.0 when I try to start it I get this error message:
Could not start Grand Theft Auto: San Andreas. Please try restarting, or if the problem persists,contact MTA at www.multitheftauto.com. [Error 5: Access is denied. (ShellExecute)]
I tried disabling anti-virus, checking/modifying permissions to files and folders both MTA and GTA SA and nothing seems to work.
However when I try to perform an update from 1.5.9 from inside of MTA to 1.6 and launch the updated version it works fine, but when I try to join a server it prompts me to update MTA and after the update the game spits this error.
My result from MTADiag:
