Invalid Signature on Package

[ccgthree]

I attempted to install the module on a host today and ran into an error indicating that the Authenticode Signature is bad:

PackageManagement\Install-Package : The module 'PSWindowsUpdate' cannot be installed or updated because the
authenticode signature of the file 'PSWindowsUpdate.psd1' is not valid.
