Has anyone gotten USART CALC to work? SERIN/OUT2 and A/D CALC work fine.

I get:
RUN-TIME ERROR 713
CLASS NOT REGISTERED
YOU NEED MSSTDFMT.DLL

I downloaded it from Microsoft,
copied into C:\Windows\System32,
Ran REGSVR32 C:\windows\System32\MSSTDFMT.DLL in RUN box.

I get:
RegSvr32 ERROR
MODULE "C:\windows\System32\MSSTDFMT.DLL" FAILED TO LOAD
THE SPECIFIED MODULE COULD NOT BE FOUND

And yet the DLL is in the folder. Any ideas? Is it looking for something else as well?
