Update 6/29 @ 11:27pm:
It actually didn’t install for me–at least not the way I thought it would. After uninstalling IE7 beta 2 and rebooting, I installed IE7 Beta 3 and rebooted again. When I then first tried launching IE, the IE window would quickly flash on and off my screen. I ended up uninstalling it and trying again but had the same results.

I uninstalled it again and did some searching. I tried again but this time I followed some of the advice I found across the web. If you’re running into the same flashing problem I was, you might want to try what seemed to work for me:

  • Uninstall IE7 Beta 2. Reboot twice. The second time actually seems to install (or uninstall) some more stuff.
  • Disable your anti-virus and anti-spyware software. 
  • Install IE7 Beta 3. Reboot twice again.

Kinda strange, but that’s what worked for me and I now have Beta 3 working just fine.
