Trouble running FM9 DLL on other PCs

Hello,

I am having trouble getting my DLL  to work on other PCs running Windows XP.

If I copy the source code over and compile it on  another machine, then it works fine on that machine. But if I just copy  the DLL over, then FM 9 crashes..

Could this be an  issue with registering the DLLs?

Thanks in advance for  your reply,

regards,
