Just Cause 2 and Win XP

[Cowsheep]

Offically not supported, i want to care about it.
The imports to the dx 10 dlls are taken via delayed imports.

At first, there is a VerifyVersionInfoA.
Xp fails, so eax is 0, Jnz after Test eax, eax is not taken -> Bad boy msg: Newer version of windows needed.
Ok, patched it.

Then, the error "Not enough storage is available to complete this operation" appears.
Why?
CocreateInstance (ole32.dll) fails with error_sxs_key_not_found, That leads directly to the error msg.

Inside that function (in ole32.dll) GetCurrentThread is called followed by OpenTreadToken.
It fails with ERROR_NO_TOKEN.

Till that point, loading a dx10 dll was not tried.


Can i break in Olly on a specific LastErr?

The error is caused by the failure of loading the file dxgi.dll. Its Vista and 7 exclusive, but i collected all substitute dlls. Nothing red in Dependency Walker anymore.

The game exe fails loading this dll with ERROR_ACCESS_DENIED, loading the dll with Olly results in "Failed to load dll" and ERROR_INVALID_NAME.

How to make the Win7 dlls loadable in XP? (All 81 substitute dlls are there, no missing function according to Dependency Walker.)

Another attemp:
I copied all dlls from my win 7 pc to on my xp pc and added the path of the dlls to the PATH variable.

Now the game accesses the dxgi.dll from C:\JC2Dlls, but that dll tries to load all substitute dlls from C:\WinXp\System32 (and not from C:\JC2Dlls)

How to stop that?
