I have a ticket in with Microsoft regarding this issue, but I thought I'd give the experts a try as well. I have a clustered Hyper-V server running 2008 R2 Datacenter and it receives the following error whenever I run Service Pack 1 RC. The error occurs right after the GUI screen "Preparing your computer..."
I have successfully installed on a node currently in the cluster that is running identical hardware and software. The system is a Dell R900.
I have run the System Update Readiness Tool and am seeing an error with package files for KB2286198_RTM. I have downloaded the update and extracted the package files. After replacing the corrupted files with the package files, the error continues. I've tried uninstalling, however, the uninstall just sits there, but doesn't seem hung.
I've attached a copy of the CBS.log file and the SURT log. CBS.log CheckSUR.log
