I installed EMET 5.0, and began to have problems with EMET shutting down Acrobat Reader, Flash, Java, Internet Explorer, and browser linkage to .PDF files.  Also,  I could not load a .PDF file directly either.  (No way to view the PDF docs for EMET!)

Error messages included "simexecflow", EAF mitigation  and need to turn off "Deep Hooks", and others.

I installed EMET about a month ago, didn't notice immediate problems, but a large set of Windows updates happened soon afterward (installed 11/8/14).  Soon after this I first noticed the problems.  I can't say for sure they weren't there before, since the time between was short.

I (I think) managed to stop the Java and Flash problems with settings, but could not get others fixed.  I finally had to uninstall EMET to fix ALL the problems !

We also have a Vista and an 8.1 machine, no problems with EMET (so far!).

I know that EMET may have problems with some applications, but it seems to me that there should NEVER be problems with these very common and essential applications.

Please either fix the problems with EMET, or tell me specifically what's needed to make these apps work with Windows 7 and EMET.

This machine has been thoroughly checked for all manner of malware, including rootkits.  All clear.

Thanks!

Microsoft released EMET 5.1 on November 10th which fixes compatibility issues with those programs under EMET 5.  Here's the information on the fixes: http://blogs.technet.com/b/srd/archive/2014/11/10/emet-5-1-is-available.aspx.

"Several application compatibility issues with Internet Explorer, Adobe Reader, Adobe Flash, and Mozilla Firefox and some of the EMET mitigations have been solved."

When Updating from 5.0 to 5.1 be aware of this:

EMET 5.1 crashes all protected applications on Lenovo m91p PCs with enabled VT and TxT

EMET 5.1 crashes Viso 2010 since of this week, please fix! (Win7 @ Lenovo TP)
Hasn't seen the problem before....
