Hello!

I'm trying to open gta_sa.exe from a script in C++... the problem is... it just starts the process (verified in task manager) but nothing happens... I tried using ''system'' function and still nothing happened. When I try open another .exe files it works... What's the problem?

Hard to say, since you don't show any code.

Did you try setting the working folder to the executables folder? Could be that gta_sa.exe tries to read files from its folder.

Isn't that... gta_sa.exe it's in the right folder with all it needs.... I just paste the directory into

the parameter. When I run it by double-cllicking it... it work perfectly, but when I run it through the

function... it just opens the process, but nothing happens. Ignore the InjectDLL_EAX and others... I tried something non-sense

Try with ShellExecuteEx, and set lpDirectory to the path “C:\\Users\\alexm\\Desktop\\GTASanAndreas”.

If that doesn't work either, check in the Event Viewer if there's any hint on why it doesn't start up.

just out of interest, why are you trying to run it from c++? why not from the command-line as it was intended?

The script he's building is injecting some DLLs, seemingly to do with vorbis.

Maybe he's trying to replace some sound files with some vorbis files he has?
