I have an Acer Aspire with windows 95 on it. I am trying to install windows 98. It starts by stating that I have Windows 95 do I wand to upgrade, and I tell it yes. Then it goes to analyse my system and it stops when it says it is going to start the windows wizard. It will not go any farther. I have shut off my screen savers and removed my anti-virus program. What should I do to get it to install?
