What is the solution to "steam failed to initialize" error in gta5?

The most common cause for these errors is an incorrect installation of Social Club. If you are receiving one of these errors,uninstall the Social Club and then reinstall it manually.When installing the second time:

• First, be sure GTAV is not running in the background. Open the Task Manager and end the following processes if they are running (right click the process and click "End Process"): GTA5.exe,PlayGTAV.exe,GTAVLauncher.exe
• Ensure you have administrator rights on your computer. Run the Social Club Installation application as an administrator by right clicking the application and choosing "Run as Administrator."

If you are still experiencing the same problem, please try the additional troubleshooting below:

• Verify the Steam Cache (Steam version only):

1. Load Steam.
2. From the Library section, right-click on the game and select Properties from the menu.
3. Select the Local files tab and click the Verify integrity of game cache... button.
4. Steam will verify the game's files - this process may take several minutes.

• Temporarily disable antivirus/security, then uninstall if disabling does not work as a test. Be sure to reinstall and re-enable your antivirus after the test.
