Fix IE9 appcrash on module igdumdx32.dll

/in

Caution! This is for Geeks only! Hide the Children!

I was holding off upgrading my laptop to IE9 and finally today the Windows Update made its way to me. I’m running an HP G60 and Windows Vista. So I apply the IE9 update and guess what?

Crash.

IE9 crashes immediately on startup. Here’s the message:

So you can imagine my frustration! So now I have to wrestle with it and there’s nothing I hate more than having to spend time fixing an update gone bad.

I tried a things that didn’t work, namely, setting my IE9 settings to system default. Still crash.

So here’s the fix for the ie9 appcrash on igdumdx32.dll

and I hope it works for you too: Go to control panel, Internet options. (normally you could do this within IE but since it crashes you can’t).

Then click on the Advanced tab, and under Accelerated Graphics, check the box next to “Use software rendering instead of GPU rendering”. In other words, turn off hardware acceleration.

You then should be able to run IE9 just fine. There’s probably an out-of-date graphics driver and I’ll have to fix that next, but for now, I wanted to publish my problem and my fix.
