Windows 7 Upgrade Advisor says OO.o won't install.

I just ran Windows 7 Upgrade Advisor. I got this remark about OO.o.


       
OpenOffice.org 3.1
version 3.1.9399
OpenOffice.org
       
Uninstall first
       
You need to uninstall this program before upgrading to Windows 7. You
won't be able to install it after upgrading to Windows 7.


Is there any truth to this? Does anyone here have experience with OO.o
under Beta Windows 7?
