I have x64 version of Ex2k7 installed in my lab. I downloaded Exchange2007-KB953467-x64-en.msp of UpdateRollup 5 and upon installing, I receive an error that patch cannot be installed due to product for what it's for is missing. Quick glance at my Exchange services shows that all are running just fine.Has anyone experienced this?

Hi, First please ensure that all the Exchange Server role has apply sp1.You can check each server version from Exchange Management Console-Server Configuration. Then please check if it is 64-bit.Please check system properties to see if it is 64 based Operation System.
