I am an occasional user of Eraser and currently 5.8.8 is installed on my Win7 64 bit notebook. I had trouble with previous versions of Eraser v.6 on this machine and went back to 5.8.8 because I wanted reliable stability for my occasional use. I looks like there is enough v6 stability and experience now with Win7 to upgrade. Before I do that, help me to understand what I need to delete if anything after Win7 uninstall of Eraser 5.8.8? I just want it to be smooth the first time.
