Put it in SysWOW64 also, and see if it works, also don't copy the dill file if your doing so that may be the problem.
I don't have a folder "syswow64" anywhere in my systm, and no I am extracting, no copy pasting. I am running windows vista 32-bit
Now am getting an error saying "C:\Nexon\Combat arms\MSVCR100.dll is either not designed to run on Windows or it contained an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support"
