EMET 5.5 SimExecFlow blocking Excel & other Office opening

    Question

  • I'm having problems im trying to open Excel and EMET is giving me an error code SimExecFlow and blocking the opening.

    My PC  is running Windows 10 and EMET version is 5.5.5871.31892 this has only just started happening.

    If i open up EMET and click on the App button there is the Application configuration panel EXCEL.EXE is in the list and has ticks under all headings apart from EAF+ and Fonts.

    I did try uninstalling EMET and opening Excel and it opened fine but now i have reinstalled EMET it has stopped it working again.

    The following other Outlook programs are having the same problems: Word, Powerpoint but for some reason i can open One Note and Microsoft picture manager.

    The version im using is Office Home & Student 2010.

  • I had the same issue. In order to prevent EMET from reporting a SimExecFlow issue, I turned off ROP Simulation Execution Flow testing for Excel in the EMET GUI. That allowed Excel to continue working. Hope this helps...
