I have a Pentium II 233 with 64 Meg of RAM, and using Windows 95. A program that I bought called TweakDUN 2.22 for getting the most from my modem strongly suggest that I make a backup of my registry first before using it. It suggests using Win95 utility ERU to do so. I tried using ERU and I get this message "Could not locate file ERD.E_El". I don't want to go any further until I have the registry backed up as advised. What should I do now?
