Google MSVCR100D.dll, download it and place in it in your crossfire folder and your system32 folder. Restart pc and it should work.

You might need what he said, or directly install Microsoft Visual C++ 2010 Redistributal.
Or you could just do what he said, but instead I have the file up for download. Download the file I have attached.
Put it in this folder;
C:\Windows\System 32
And like said, restart after and try again.
