Is there a fix for a launcher error in the PC version of GTA 5?

I initially did not have this error but it appeared in one of my friends pc. The fix is simple and worked in his PC(If it didn't work for you I am sorry).Follow this steps :

1. Google this “Manual Link to Social Club Application”.
2. It will be the first link, now download the file for GTA V.
3. While the software is being downloaded make necessary changes for the software to work.
4. Click “Start” then type “regedit.exe”.
5. Navigate to “HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Rockstar Games\Grand Theft Auto V”.
6. If the “Grand Theft Auto V” folder is not present create it by right clicking the “Rockstar Games” folder and selecting “New>Key”.
7. Now navigate to the folder and inside it create a new string value, name it as “InstallFolder” and then double click the file to give it a value.
8. Inside the “Value data” give the location address of GTA V(The location where you have installed your game).
9. Now close registry editor(regedit.exe) and install the downloaded file.
10. Start the game it should work
