msvfw32.dll is missing from your computer

googling told me that msvfw32.dll could be anything (i didn't see anything helpful when googling within a year so i google all years), and some sites say redownloading is a bad idea. if i should, what's the safest source and where do you put the file?

advise please? anyone familiar and knowledgeable with msvfw32.dll?
