AutomationTool terminated with exception: Exception in AutomationUtils

Hi all,
I was building just fine then, on the next deploy I got this error continuously,
I’ve searched about but cant find any answers that fix it,

Any ideas?

Cheers in advance

This is the error message I am seeing: MainFrameActions: Packaging (Android (ETC2)): Program.Main: ERROR: Exception in AutomationUtils.Automation: You are attempting to compile on a machine that does not have a supported compiler!

Ensure that you have Visual Studio 2015 installed, including the required C++ content, and then attempt to package your project again.

Have a great day

Hi, Yep VS 2015 is installed,

I just don’t get how it was packaging fine, then literally 10 minutes later, using hte same process this error occured?

If I start a new project and package, it works fine,


Have you tried deleting the Saved and Intermediate folders from your project and packaging it again? Also, have you restarted your PC?

Are there any unresolved errors in your project that could have prevented it from completing the packaging process?

Will give the saved and intermediate folders a try,
PC has been restarted,

Only errors have been a few overlapping UV errors,

Let me know the results after you’ve removed those folders.

Folders deleted, now getting this error?

Program.Main: ERROR: Exception in AutomationScripts.Automation: Stage Failed. Missing receipt ‘’. Check that this target has been built.


Take a look at this Answerhub post, as it seems to have a few different solutions for you to try:

If these solutions do not work, feel free to reply to this thread and let me know.

Have a great day

I’m not sure how mine got fixed in the end, a lot of restarting the editor/ PC.
Think it has something to do with the builds folder, and a few other things.
Sorry =/
