If you haven’t already of course… Some early warning here to allow you to plan for any August 2012 or post August 2012 Cumulative Updates. For SharePoint Server 2010, and Project Server 2010 and the rest of the Office 2010 family you will need to have loaded Service Pack 1 (SP1) before you can install the Cumulative Update. This means really loading SP1 – not just relying on the fact that ‘almost all’ of SP1 has been included in patches since June 2011. If you remember we went through a similar stage with 2007 – and one of the most notable things is that the patch will shrink down to a much smaller size (The June 2012 roll-up patch was over 1.2GB!). I haven’t had a chance to try it out – but I suspect the error message if you haven’t loaded SP1 will be something along the lines of “There are no products affected by this package installed on this system” or “ The expected version of the product was not found on the system” – I’ll update once I get a chance to test. The reason behind this change is to do with our product support lifecycle (see Microsoft Support Lifecycle ) and the fact that we have reached what we term the end-of-life (or service pack support end date) for the original release of the 2010 Office family – which is around one year after release of Service Pack 1. For most customers you could see this first with the August 2012 Cumulative update – which will be something like build 14.0.6124.5000 – or potentially before if there are any special releases before that release (and after the June CU) – which would be something like 14.0.6123.5003. Other customers who do not necessarily load all cumulative updates may run into this much later, as it will be the ongoing requirement for future Cumulative Updates until the next service pack support end date – approximately one year after SP2 (and no – I do not know when SP2 will be coming along – before you ask!). Excellent references for Service Pack 1 can be found at the new-look Project blog - Announcing Service Pack 1 for Microsoft Project & Project Server 2010 , for the initial announcement, Announcing The Release Of Service Pack 1 (SP1) for Microsoft Project and Project Server 2010 for the release notification and particularly the TechNet article at http://technet.microsoft.com/en-us/library/hh272536.aspx - Deploy Service Pack 1 for Project Server 2010. And finally – to find out if you already have SP1 installed I’d suggest going to Control Panel, Programs, Programs and Features, Installed Updates – and you should see it listed there – Microsoft SharePoint and Project Server 2010 Service Pack 1 (SP1) http://support.microsoft.com/kb/2460047 .
