I may be wrong to some degree.Go to seach and type mscdex.bluto said:Xp does not need mscdex,that's old Dos history.
When it did the install disk would write something like this to your Autoexec.bat file.
LH/L:136340D C:\cdrom\mscdex.exe/C:mscd001
mscd001 is the name of the driver.
This is history man,start over.If it's warranted take it back.If you bought a package then this post is hard to understand.
If its not in C:\Windows\Command,I will email it for you to put there.
25 bytes.Relax man.
Just remember i have WMe.not XP.
But did you try Control Panel/Install new hardware ?
