vfp7t.dll was on the machine, but not registered. Once I registered it, the other DLLs registered correctly.

Thanks all

>Did the machine that failed have the vfp7t.dll, vfpenu.dll, yourdll.dll, yourdll.tld, yourdll.vbr, and the c++ ver 7 runtime?

>>"DLL RegisterServer in myDll.dll failed. Return code was: 0x80004005"

The machine that failed, did have the VFP prerequisites installed, but not the IDE.
