Can't load the DLL #38

Closed keyile closed 5 years ago

keyile commented 5 years ago

Hello, I' m using this patch for Red Alert 2. I put ddraw.dll in the same directory as the executable file, but nothing really changed, and the ddraw.log didn't appear. I think maybe the DLL file isn't loaded at all? Why does this happen?

I'm using Windows 10, thx.

You can use tools like Process Explorer to check which DLLs are loaded by a process, and also to verify if the game executable is where you think it is. What does it show?

I have the game from Origin and it works fine with DDrawCompat here on Windows 10.

Yes, thanks for telling me the perfect tool, I find the problem. The executable is game.exe, and it loads the C:\Windows\SysWOW64\ddraw.dll, which is undesirable.

The solution is to delete the ddraw.dll entry in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\KnownDLLs in the registry, so the program can find the patched version of ddraw.dll.

Thanks again, for helping me, and for your brilliant job!
