Scroll down to find , expand it, and check the box for "DirectPlay" . Click OK and restart your computer to apply the changes. 3. Run in Compatibility Mode
: For example, C:\Program Files (x86)\ Rockstar Games \Grand Theft Auto Vice City .
Check and select Windows XP (Service Pack 3) or Windows 7 . Check "Run this program as an administrator" . 4. Reinstall the Game
If the DLL file was missing from a "broken" installation or a faulty download, the best path is often a clean reinstall.
If the DLL replacement doesn't work immediately, your Windows version might be too new for the game's executable. Right-click on the game's .exe file (e.g., gta-vc.exe ). Select > Compatibility tab.
To get your game running error-free, follow these steps in order of effectiveness: 1. Replace the mss32.dll File
The most frequent cause is a corrupt or incompatible mss32.dll file. Replacing it with a version specifically compatible with your game and modern Windows versions often fixes the issue.
