Can't install Acronis 2013, Norton Internet Security 2013 and a reinstall of my HP printer. My printer is not working; a reinstall failed. I have a terrible feeling that I ruined the Registry the other day when I tried to uninstall a program with Revo Uninstaller. I know that only bold face boxes should be deleted in Revo but I remember inadvertently clicking on a bold box "My Computer."
I've done sfc /scannow, chkdsk/r, etc., Window Installer in Services to make sure it's on, etc. I've always been in mortal fear of fooling around with the Registry--won't go near it, but the prospect of a clean install (Windows 7 64) makes my hair stand on end. Will appreciate ideas from your collective brilliant brains. ellen
