Plug-in not registering

[voidstar]

Hi,

I have made my own Winamp plug in for a module (somewhere in between .MOD and .MID) format a friend and I have been programming. The plug-in compiles and runs correctly on my computer. However, Winamp doesn't see the plug-in on any other computer.
So, on my computer, I place the plug-in in the winamp/plugins directory, restart Winamp, and it works - I can play my files.
But on other computers, I place the plug-in (in_duh.dll) in the winamp/plugins directory, restart Winamp, but now winamp doesn't show the plug-in in the plug-in list.
We tried flushing hte plugin name cache, and reinstalling Winamp, but nothing seems to help.

We're all using Winamp 2.76.

I am under Win2k, and I compiled it with MSVC 6 pro sp5. The others are under Win98 or Win98SE.
I used the depency finder tool, but the plug-in only relies on kernel32.dll, user32.dll and msvcrt.dll, which are installed on all the computers that have been tested.

Thank you for your help.

link statically to msvcrt (project / settings / c/c++ / code generation / run-time library : multithreaded) or make sure that others have the same version of msvcrt.dll.

That didn't work
I get the error:

LIBCMT.lib(crt0.obj) : error LNK2001: unresolved external symbol _main

For reference, I switched from Debug Multithread DLL to Multithread DLL, and it worked.
Thanks for the help anyway!
