Dentrix Enterprise

I think we should have the option to uninstall enterprise 7.0. I am able to uninstall 6.0 just by going through the install process and it give me the option to uninstall 6.0 or not. I do not have that option in 7.0. The only other option I can think of would be to go into the registry and remove it that way but that would be a big pain. I also checked in add and remove programs but it's not there either. I am talking about removing it from a workstation not a sever just to be clear.
