do you have a key for it? if you do, just delete the symbols and restart it, it will download the newer ones that you need Thanks. I didn't have a key but have since donated and everything works great. With this, start8 with the win7 start button and xXiNightXx's Aero 8.1 theme, you'd never know you updated from win7!

Aero Glass RC1 worked for me on a fresh install of Win8.1 RTM. But the first time I went to Windows Update and installed updates and rebooted, it broke - dwmcore.pdb is mismatched and so was udwm.pdb. It only accepted dwm.pdb.
