I have now install c++ Redistributable 32 bit, and it works. But i can still not load LCPDFR in-game :(
I runned a Diagnostics and it says:
NET Framework 4.0 installed: True
Visual C++ 2010 Redistributable installed: False
GTA IV - Installed: True
GTA IV - Install folder: D:Grand Theft Auto IV
GTA IV - Version: 1, 0, 7, 0
GTA IV - Asi loader installed: True
GTA IV - Asi loader: DSOUND
GTA IV - Asi loader valid: True
GTA IV - C++ ScriptHook installed: True
GTA IV - C++ ScriptHook valid: True
GTA IV - C++ ScriptHook version: 0, 5, 1, 0
GTA IV - ScriptHookDotNet installed: True
GTA IV - ScriptHookDotNet valid: True
End of *SIGNED* LCPD First Response Issue Report
But then i try to reinstall LCPDFR it says i have installed Visual C++ redistributable. It doesn't make sense.
