Helping people with computers... one answer at a time.

It's unclear where MSSTDFMT.DLL comes from, but if a "memory optimization" program is asking for it, I'm very skeptical.

I want to install a memory optimizing program but it will not work without a .dll file; more specifically "MSSTDFMT.dll". How do I get it?

I'd start off by questioning that memory optimization program. It should either:

  • rely only on standard windows components

  • install everything it needs

  • or tell you where to get the pieces it needs

So I'm a little skeptical about whatever it is you're trying to install.

That being said, you may already have the file on your machine. Use search for files to find it. If it's found, you may be able to get things to work by executing "regsvr32.exe msstdfmt.dll" in Start, Run.

If you can't find it you may be able to get it from a Windows XP CD-ROM, or from a couple of download sites on the internet. Just do a Google search on "msstdfmt.dll". You may still need to run the regsvr32 command I mentioned above after downloading it.
