MissingMethodException at E-Mail-Router installation

This week I’ve installed the E-Mail-Router for a customer. During the setup an error came up

Action Microsoft.Crm.Setup.Exchange.GenerateEncryptionKeyAction failed.

Method not found: ‘Boolean Microsoft.Crm.ApplicationConfig.IsFederalInformationProcessingCompliant()’.

The cause of this error was a pending restart which was requested by Windows Update. I have no clue if a specific update was the cause of the problem, or the system state itself.
However, after rebooting the machine, the error went away and the setup was successful.

So keep in mind, if the pre-checks warns you about a pending reboot, it is sometimes better not to ignore this hint 😉
