title: Visual Studio 2015 Excel Debugger not working
body: <p>A few weeks ago my Visual Studio 2015 excel debugging just stopped working and it's driving me crazy.</p>
  
  <p>So, this is the problem, I create an empty Excel Ribbon, no logic, just the stubs and I hit the debug button. VS starts excel and whilst loading following Exception pops up:</p>
  
  <blockquote>
    <p>Managed Debugging Assistant 'FatalExecutionEngineError' has detected a problem in 'C:\Program Files\Microsoft Office 15\root\Office15\excel.exe'. Additional information: The runtime has encountered a fatal error. The address of the error was at 0x73921620, on thread 0x1674. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack.</p>
  </blockquote>
  
  <p>Since I am using my work's laptop, my guess is that an office update has been installed and broke VS, but there is nothing I can do about that.
  I already reinstalled VS and updated it to the latest version.
  If I start the Ribbon without debug settings, it works just fine.</p>
  
  <p>I am using Office 15.0.4797.1003 and VS 14.0.25123.00 Update 2</p>
  
  <p>Do you guys have any idea?</p>
