Universal Print Connector Error when registering Printers

[Ron Mckerral]

Hello,

I've installed the PrintConnector on our Print server, when I try and register any printers (HP, Canon, Sharp,ect).. It comes up as failed. In the event viewer, we see (listed Below)

Has anyone else seen this or may know a way around it? I tried on a second Print server and same results.

Thank you,

Does the machine where the connector is installed meet the prerequisites outlined here: http://aka.ms/InstallUPConnector ?

This is an expected error if the pre-reqs are not met. Older OS versions don't have the required APIs. Hence, the "MissingMethodException".

Thank you, that was the problem. It didn't meet the server requirements.

Thank you,
