Hopefully someone has some insight as to what may be causing this.
Our VMware Administrator has given my Windows domain account the permissions listed in the Developer's Guide. However I've been unable to build a VA to this point using VMware Studio v2.6 on vSphere 5.1. The error along with the preceding log is listed below. I can however successfully create a standard VM on vCenter using the vSphere Client.
