I tried reinstalling but that didn't help. I looked at the code and the Get-AuthenticodeSignature call is attempting to use PowerShell. I work at a utility company and then don't allow a non admin id to run powershell commands as part of their security procedures.
I'll open a support case at the address above. This seems like a poor decision on EverNotes part to assume all users will have access to PowerShell or in my case force me to run EverNote with elevated privileges.
