My IE 10 crashes with EMET 5.1 installed.
If I uninstall EMET 5.1, then IE10 works.
Anyone else having this problem?
Oddly, this problem only appears on some of my computers.
Problem *SEEMS* to be more prevalent when EMET is running with VMWare.
I'm using VMPlayer, and VMWare ESXi host.

Did you try if the problem remains if you start Internet Explorer with the '-extoff' parameter? Maybe there is a difference in the installed extensions between the computers.

Uninstalling EMET 5.1 is the most drastic 'solution' for your problem. You could delete the Internet Explorer application from the list of apps but this would disable the other protections for IE. You can also disable the EAF mitigation on the problem system specifically to solve your problem.

I agree with you that EMET causes more problems on virtual systems.

Tried it just now by going to c:\program files\internet explorer
Then I typed: iexplore -extoff

Still getting the same error.

I closed all applications, and then disabled all mitigations for internet explorer inside EMET, but I'm afraid that the problem persists, even after trying -extoff again.

Maybe your virus scanner is conflicting with EMET. According to this post Comodo Antivirus seem to cause problems with EMET. The DeepGuard functionality of F-Secure virus scanner  is also incompatible EMET according to this post.

Thanks for looking further into this, however, I intend to keep Comodo AV for the foreseeable further.

Hopefully future versions of EMET and Comodo will be compatible with each other.

Thanks.

According to this post 'Re: EMET 5.1 with CIS 8?' EMET 5.1 seems to work with CIS8. If your version isn't working can you upgrade? If not maybe you can contact Comodo support if they have a patch. You can also send an email to emet_feedback@microsoft.com or leave your feedback through Microsoft Connect for EMET (https://connect.microsoft.com/emet/Feedback).
