I have a program that uses the oMapiSession and oMapiMessage active X controls from msmapi32.ocx. Works fine under XP, Vista, etc. But when installing to SOME Windows 7 machines, it simply gets to the .SEND() command and does nothing. No error code, simply skips by it.

I've registered it by using a command line "run as administrator" and typed in: regsvr32.exe msmapi32.ocx. It succeeded.

It does work on some Windows 7 machines, just not on others. Any ideas or roads i can go down?
