2 programs need to use a dll file in the same folder...

[Vikerules]

So i have 2 addons for a game, both addon files need to be in the same folder and both programs need a dll file which also need to be in the same folder, thing is i cant have 2 "d3d9.dll" files in the same folder. What can i do to make both addons work and not just one or the other?

Both need to use their own custom d3d9.dll
if neither will work with the others d3d9.dll, you are stuck

Things to try: (you have likely tried these anyway but still)
Try with original d3d9.dll
Try with addon 1's d3d9.dll
Try with addon 2's d3d9.dll

If it wont work, it wont work unless you somehow manage to change it (one of the add-on's) so that other uses renamed d3d29.dll or something. (it likely wont work)
