See if Re: Cannot create MSMAPI.MAPISession Message #1029060 helps?

The only thing I find missing is MAPIR.DLL located in the C:\Program Files\Common Files\SYstem\MSMAPI\1033\MAPIR.DLL. I moved that file into the location (copying from Dev) and tried a regsvr32.exe. I get the DLLEntryPoint Server Not Found error when attempting to register. The license error still occurs in my application on the test machine. I can not find any information on what MAPIR.dll does in terms of MAPI
