FatalExecutionEngineError after Windows 10 Anniversary Update RRS feed

  • User798808059 posted

    After installing the Windows 10 Anniversary Update (and re-installing IIS, since the update removed it), we are unable to run our local development websites in IIS 10.

    Now, whenever we attempt to access on our local dev websites through a browser, we see the following:

    In the event log, we see corresponding errors like the following:

    Log Name: Application
    Source: Application Error
    Date: 9/22/16 10:57:46 AM
    Event ID: 1000
    Task Category: (100)
    Level: Error
    Keywords: Classic
    User: N/A
    Computer: DANIELKLEIN232E
    Description:
    Faulting application name: w3wp.exe, version: 10.0.14393.0, time stamp: 0x57899b8a
    Faulting module name: clr.dll, version: 4.6.1586.0, time stamp: 0x575a1507
    Exception code: 0xc0000005
    Fault offset: 0x0000000000099a99
    Faulting process id: 0x1270
    Faulting application start time: 0x01d214ea0ede0a43
    Faulting application path: c:\windows\system32\inetsrv\w3wp.exe
    Faulting module path: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\clr.dll

    Faulting package full name: 
    Faulting package-relative application ID: 
    Event Xml:

    Furthermore, I have debugged one of the web sites -- watching in the debugger, we make it through the Application_Start just fine, but then immediately thereafter the exception is thrown. We originally thought this was related to #1583, so we tried installing/repairing .NET Core as well as repairing VS2015, to no avail.

    We are at a complete loss -- any help and/or a workaround would be greatly appreciated. Until then, we are all going to roll back to prior to the Anniversary update.

    Crash dump analysis might reveal the exact cause and then the solution can be found. If possible, open a support case via http://support.microsoft.com

    Hi Dmarklein,

    I suggest you use .NET Framework Setup Verification Tool to check if the .NET Framework is ok. If you find there is anything wrong with .NET Framework, you may use Microsoft .NET Framework Repair Tool to do a repair, This tool detects and tries to fix some frequently occurring issues with the setup of Microsoft .NET Framework or with updates to the Microsoft .NET Framework.

    Check Programs and Features in Control Panel: If Webcompanion by Lavasoft is installed on your machine, then uninstall it and restart your machine. Try bringing up a local site in your browser to confirm the problem has been fixed.
