Installation Message when trying Rollup 2 on Exchange 2010 Service Pack 3
When you are trying to upgrade Microsoft Exchange 2010 SP3 to Rollup 2. You can get a message that Rollup 2 is looking for the file Exchangeserver.msi ( this is a file which you can find in the Service Pack 3 installation files). So to remember when you upgrade to Rollup 2 of Service Pack 3 for Exchange 2010 you need to have the Service Pack 3 installation file ready.
When I see the message again I will try to make a print-screen.
On the Microsoft Windows Essentials blog you can find the pictures. http://blogs.technet.com/b/sbs/archive/2013/08/30/installing-update-rollup-2-for-exchange-2010-service-pack-3-may-fail-or-prompt-for-installation-package-source.aspx
