Solution #1: This is the easy way, you just right click on SA-MP.exe and click run as administrator, it may ask you to prompt the access as an administrator (if you have UAC/User Account Control to set to high or medium as it asks you to confirm that you wish to run an application as an administrator), click confirm/yes. SOLUTION: There are two different ways to fix this issue, the easy way or the long way: The issue occurs when San Andreas Multiplayer is unable to launch a few files from the game or the GTA San Andreas User Files.
