    I have installed RU5 V2 on all our exchange servers but the customer wants to roll back to ru4 v2 because of EWS issues. I have uninstalled RU5 V2 from all servers with the hub role only. But when I go to uninstall from a server that has the Hub,Cas,MBX role it tells me it cannot find exchangeserver.msi I have the RU4 V2 msp file available. I have seen all the articles about the execution policy but they haven’t helped. Any additional advice would be appreciated.
