Environment

Cause

The $GOPATH shown above in the Symptom does not execute successfully because you need to have PowerShell v5 to create the Windows Stemcell but this version is not applied.

Resolution

First you need to install the BOSH PS Modules according to the following documentation: https://docs.pivotal.io/pivotalcf/2-3/windows/create-vsphere-stemcell.html#bosh-ps-modules

After Step 4 in the Install the BOSH PS Modules section in the documentation, or after Unzip the archive with the following command, please run the following function in Windows VM, derived from BOSH PS Modules.

Upgrade-PSVersion

Now the version of PowerShell is upgraded to v5 automatically and Apply Changes won't fail. 

IMPORTANT NOTE: You then must must proceed with the remaining steps in the above documentation. In other words, install the Cloud Foundry Diego Cell requirements.
