Windows drivedb update script returns "gpg.exe gpg.exe is not recognized..."

[Adam Piggott]

When I try to execute the update-smart-drivedb.ps1 script in a Powershell or Command Prompt CLI (running as Administrator or not) I receive the error:

& : The term 'gpg.exe gpg.exe' is not recognized as the name of a cmdlet, function, script file, or operable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
