I have not found alternative methods to send mail from Office via smtp.
VBSendMail works fine with Win64bit-Office32bit but gives "Interface not registered" error with Win64bit-Office64bit.

On the same pc the example executable "SendMailExample.exe" works but from office (64 bit)
Set poSendMail = CreateObject ("vbSendMail.clsSendMail")
returns the "Interface not registered" error.
Do you have any idea how to solve the problem?
