This is a Microsoft Standard Data Formating Object DLL
Here's what needs to be done:
Copy the MSSTDFMT.DLL to c:\windows\system
and go to a cmd prompt and enter the following:
Back up your current copy of MSSTDFMT.DLL and copy the new version to the same file location. This file should be located in the WINDOWS\SYSTEM directory on your C: drive (for Windows NT, 2000, and Xp: \WINNT\system32).
Using your mouse, click on the "Start" button and then click on "Run".
Type the following command to register this library file: regsvr32 \windows\system\MSSTDFMT.DLL (for Windows NT and 2000: regsvr32 \WINNT\system32\MSSTDFMT.DLL)
You should see a message saying "DllRegisterServer ... succeeded"
If you are getting an error telling you that the file is missing, then you are not typing the command in correctly. You will need to type it in *exactly* as follows:
regsvr32 \WINNT\system32\MSSTDFMT.DLL (for Windows NT and 2000)
* Please note that there is a SPACE after "regsvr32" and before "\windows\system\MSSTDFMT.DLL"
You should probably copy and paste the command so that you are unable to mistype it.
