Another day, another failed install...
Today I tried booting Windows 7 into safemode with networking and running the cleaner tool, renaming folders. Reboot to normal mode, disable UAC and downloaded a fresh copy of the AAM 7 installer.
AAM 7 installs ok and when opening it up it does not try to update like it did before, but it does show the CC apps in the list.
However trying to install a CC app just fails.
I did do the reboot and try install again thing, but it just failed again.
Hope Adobe finds a solution for this soonish. Not too excited about the way this is handled.
