Quicktime reverting Vista to 16-bit Windows Vista Basic theme

[Guest afairjudgement@gmail.com]

So I think what caused this to happen is from my regretful attempt to

get some of the old Myst games working *Myst masterpiece edition +

Riven), and this HAD to install the old version of QT that they used

(can't remember version number). Now since then, whenever I go to do

anything involving quicktime, it set my Vista theme to Vista Basic and

as soon as I close it, it reverts back to the Aero theme.

Not sure what to look for...I've uninstalled all versions of Quicktime

then reinstalled from the web installer. Maybe I need some sort of

registry cleaner but I don't trust many of em.

Just need some suggestions...thanks
