Automatic upgrade of Tentacle fails

I added a listening Tentacle of version 2.5.6 to my Octopus environment which is 2.5.7. When I attempted to automatically upgrade from the Octopus UI, I received this error:

`Running PowerShell script: E:\Octopus.SQ-STUFF-7D7D4779\Octopus.Tentacle\\Deploy.ps1

Both machines are Server 2012 R2 and Octopus is installed to the E:\ drive. I’ve manually installed the upgrade for now, but it would be nice to have this work in the future :slight_smile:
