IE9 crashes on startup on 32-bit Windows 7

I've just finished installing IE9 on my windows 7 32-bit machine. It appeared to complete ok- no errors or warnings in the event logs.

However when I try to run IE9, the window opens, the blue loading circle spins, "not responding" appears, then the window shuts without anything appearing in the browser window.

My machine is a decent spec, and I've had no problems with IE8, or any other browser before.

Here are the things I've tried which didn't help:

  • Installing IE9 via Windows update, instead of manually
  • Running in "no add-ons" mode
  • Disabling all add-ons manually
  • Running the OS in safe mode
  • Temporarily disabling firewall/antivirus
  • Resetting IE settings in "Internet Properties"
  • Ticking "Use software rendering instead of GPU rendering" in "Internet Properties"
  • Re-registering dlls
  • Running program as administrator
  • Installing SP1
  • Installing all critical/important windows updates
  • Logging into Windows as different user
  • Downloading the installer using a different machine (in case installer was corrupt)
I am now officially out of ideas. Anyone got any more?
