Trying to install Rollup 7 on a Windows Server 2008 R2, system running Exchange 2010 SP3 Rollup 6.
Problem – error code 1603
The installer for Exchange 2010 Rollup 6 has failed and has returned error code 1603.
NetApp filer was updated to OnTAP 8.2.1.
I had upgraded SnapManager for Exchange to version 7.0, which required Powershell version3.0, which is not compatible with Exchange 2010. So, after the un-install of SnapManager v 7.0 and uninstall Powershell 3.0 (KB2506143), I restarted the system. I ran the rollup successfully and installed SnapManager for Exchange version 6.1. I restarted the system and all was well.
What to look for:
Check you installed updates in the Control Panel for KB2506143. You will need to remove this and restart, before you can proceed with the install of Rollup 7, or any Rollup for that matter. I hope this information has helped one of you out there.
