SQL Server 2012 - applying SP2 breaks SSRS Report Builder

Question

Hi,
Had SQL 2012 (was 11.00.2845) and SSRS configured and working.  
Applied SQL 2012 SP2 (server now at version 11.0.5058.0 (X64).
But when I goto the typical "http://server/ReportS_INST1 - reports still work ok, but clicking on Report Builder looks like it starts the download and then errors.  
The error is "Application validation did not succeed.  Unable to continue.".
Clicking on Details gets the message below.  I understand it thinks it has a version mismatch, but anyone know what the resolution should be?
Thanks
Matt

Hello,
It seems to me somebody applied SP2 for SQL Server 2012 on an instance that has installed SQL Server 2012 SP1 CTP 4. CTP4 is not
the final version of SP1.
http://sqlserverbuilds.blogspot.com/
My suggestion is to uninstall SP2 (using Control Panel), download and apply SP1 from the following link, and then apply SP2 again.

Hope this helps.
