When I unzipped the files from MPEG4.zip, there was no .exe to install, just the following SIX files: divxpatch.txt M$mpeg4.inf Mpg4c32.dll Mpg4ds32.ax Msaud32.acm Readme.txt Had already moved the two files you suggested to the windowssystem directory--with no luck. I'll keep trying to figure it out. Is it possible that my zipped version has no install file?
