Alteryx Crashing - Visual Studio Just-In-Time Debugger


Hello Everyone,

I just upgraded our Alteryx Designer yesterday to 2019.3.2.15763 and today when our scheduled workflows were supposed to run, they are failing with the Visual Studio Just-In-Time Debugger error message.  It appears to only be on workflows using the CReW Runner macros. 

"An unhandled win32 exception occured in AlteryxRunner.exe [14864]. Just-In_time debugging this exception failed with the following error: No installed debugger has Just-In-Time debugging enabled.  In Visual Studio, Just-In-Time debugging can be enabled from Tools/Options/Debugging/Just=In-Time. 


Check the documentation index for 'Just-in-time debugging, errors' for more information."





Thank you,



I'm having the exact same issue.  All my overnight jobs that use runner failed.  


I tried downloading fresh macros and uninstalling and reinstalling, but same issue.


I also reinstalled 2019.3, but have the same issue.  


Now looking into rolling back to 2019.2


I think the issue is with the executable that runs inside the AlteryxRunner macro.  Called AlteryxRunner.exe.


If i just manually try to run this it gives an error saying that AlteryxEngine.DLL is missing.  It's still in its normal place though.


Not sure if that helps




So I installed 2019.2 and now the runner is working again.


That is exactly what I had to do and it is working right now.  I can submit a ticket to make sure they aware of the issue.


Thank you!


The 2019.3.5 Stable Update is now available for download and includes this fix.
