I installed and uninstalled Exchange2010-KB2986475-x64-en and then when v2 was released I tried to update to this version. however I am facing a 1603 error each time I run the installation. I enabled logging and I am seeing the following error:
Property(C): msgRequiresProc = The version of this file is not compatible with the version of Exchange Server 2010 that you're running. Check your computer to see whether you need an x64 (64-bit) or x86 (32-bit) version of this file.
Property(C): msgINTERIMUPDATEDETECTED = Unable to install because a previous Interim Update for Exchange Server 2010 has been installed. Please use Add/Remove Programs to uninstall the Interim Update before running this setup again.
However there are no interim update installed that show in the add-remove programs. I have now uninstalled SP3 CUR 7 as well, but with no results. In addition attempting to reinstall cu7 results in the same message in the log as above. Can anyone point me in the right direction to finding the blocking update or flagged registry key that is now preventing installation of the rollups?
Thank you
