The Powershell requirement for Discovery Product has changed in Orlando. It needs minimum Powershell v3.0 to function correctly.
Run a MID with PowerShell version 2. There is no notification message on the MID server record warning you are using an out of date version.
This problem has been fixed. There is no workaround available. If you are able to upgrade, review the Fixed In section to determine the latest version with a permanent fix your instance can be upgraded to.
There is no need of applying workaround for the notification purpose. SN recommends customers to upgrade to the supported Powershell version 3.0-5.1 on MID server host.
