I have installed avast! on Windows Vista Beta 2 (x86) and entered my key as usual. But when i wanted to update i got error that my license expired. W00t, i check the About box and it says expires on "1 june 2006" even though this very same license should last for much longer, most certanly till May 2007 if i remember correctly.
I know Vista isn't ready as well isn't avast! but feedback can't hurt right?
