Since using CCleaner on the registry, I can no longer update software or install new software. Keep getting the Error 1402:Cannot open key...you do not have permission. I'm in over my head. Help, please.

Which software are you referring to??
Try a System Restore providing you haven't cleared out your restore points.

Or you could restore the REG backups that CCleaner creates when changing the registry.
and from now forward please follow the advice in my signature and do not clean everything that comes up on the registry clean
