I have followed every tip and suggestion I can find including SFC / SCANNOW & System Readiness Tool. I know what the problem is, just not how to fix it. The System Readiness Tool detects corruption in two previous patches as follows: Checking Package Manifests and Catalogs (f) CBS Catalog Missing 0x00000002 servicing\Packages\Package_237_for_KB2633952~31bf3856ad364e35~amd64~~6.1.1.0.cat (f) CBS Catalog Corrupt 0x800B0100 servicing\Packages\Package_for_KB976002_RTM~31bf3856ad364e35~amd64~~6.1.1.14.cat and it goes on to say Checking Packages (f) CBS MUM Missing 0x00000002 servicing\Packages\Package_217_for_KB2633952~31bf3856ad364e35~amd64~~6.1.1.0.mum (f) CBS MUM Missing 0x00000002 servicing\Packages\Package_for_KB2633952_RTM~31bf3856ad364e35~amd64~~6.1.1.0.mum Checking Component Store (f) CSI Payload File Missing 0x00000000 oleaut32.dll amd64_microsoft-windows-ole-automation_31bf3856ad364e35_6.1.7601.21802_none_1bb89fec2b3108e2 Summary: Seconds executed: 675 Found 5 errors CSI Payload File Missing Total count: 1 CBS MUM Missing Total count: 2 CBS Catalog Missing Total count: 1 CBS Catalog Corrupt Total count: 1 Unavailable repair files: servicing\packages\Package_237_for_KB2633952~31bf3856ad364e35~amd64~~6.1.1.0.mum servicing\packages\Package_for_KB976002_RTM~31bf3856ad364e35~amd64~~6.1.1.14.mum servicing\packages\Package_217_for_KB2633952~31bf3856ad364e35~amd64~~6.1.1.0.mum servicing\packages\Package_for_KB2633952_RTM~31bf3856ad364e35~amd64~~6.1.1.0.mum servicing\packages\Package_237_for_KB2633952~31bf3856ad364e35~amd64~~6.1.1.0.cat servicing\packages\Package_for_KB976002_RTM~31bf3856ad364e35~amd64~~6.1.1.14.cat servicing\packages\Package_217_for_KB2633952~31bf3856ad364e35~amd64~~6.1.1.0.cat servicing\packages\Package_for_KB2633952_RTM~31bf3856ad364e35~amd64~~6.1.1.0.cat I need help. as it stands SP1 will not go on.

1. Are there any detailes in WindowsUpdate.log, ReportingEvents.log and event logs? 2. There is possibility to install update manually: http://support.microsoft.com/kb/2633952/en-us 3. Give a try to clean boot. 4. Disable browser choice in msconfig Regards Milos

Hi, Before moving on, I would like to know how to install the updates, via Windows Update or WSUS? Kim Zhou TechNet Community Support
