Rockstar released the first patch patch for GTA 5 which weighs in at 207MB on Steam but has it fixed your problems?
As expected the first patch for GTA 5 has been released and your copy should update on Steam with a 207MB patch, and if you’ve not purchased it through Steam, the patch should be around 352.75MB plus a 53MB update.
What the patch actually fixes is not completely clear as no patch notes have been posted by Rockstar at the time of writing.
There are two things we know have been rectified in this update, the already announced Windows user name issue and it also appears they have resolved the problem with the GTA launcher chewing up the CPU which means there should be no need to reduce the priority of the launcher in Windows Task Manager.
This patch seems to be showing some really mixed results with some users now experiencing stuttering issues that were not happening prior to the patch. There are also still reports of crash problems so it appears the patch may not have fixed some of the more serious problems players have been experiencing and many players are having difficulty actually getting the patch downloaded.
If you are having problems with the “unavailable(Code 12)” after the update, try running the GTAV.exe, GTAVLauncher.exe, and PlayGTAV.exe as Administrator. You can set these exe files to run as Administrator by changing them in your file manager with a right click on the file then selecting “Run as Administrator”.
We’ll post any patch notes up in this new item should they appear but do let us know if this update has fixed or even broken the game for you.
Edit: Patch notes for 1.01 are now available to read.
