to register a DLL in Windows
You may enter to an error like "Error MSSTDFMT.DLL Class not registered".
In this case register the DLL as follows.
Open a command window
(cmd.exe) running as an Administrator
(This is easiest
to do if you create a short cut to cmd.exe, then click the shortcut with
mouse right button - Run as administrator)
Go to the folder
where the DLL is located eg. "cd \windows\syswow64"
Register the corresponding
DLL eg. "regsvr32 msstdfmt.dll"
