Hi,
I am trying to install Exchange 2010 SP2 Rollup 5v2 but it keeps failing on one of the CAS servers. I am using command line with Run as administrator. I enabled the windows installer logging. That log gives the following error: -
==================
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.
Property(C): ButtonText_Remove = &Remove
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.
===========================
There is no interim update installed on the server. The last update was Exchange 2010 SP2 Rollup 3. On other CAS server it installed successfully that server also has Exchange 2010 Sp2 Rollup 3.
Server is win 2008 R2 SP1 64bit.
Is there any other way to find out what exactly this installer is seeing that I am not seeing?
Thanks,
Raman
