Hi,

I am running Windows Vista Home Premium on my laptop. For last few days I have been trying to install 'Upadate for Microsoft Silvelight (KB979202)' without any luck. Each time, I get the error "WindowsUpdate_00000652" - Windows Update Encountered an unknown error. However, in between, another update (KB915597) has been installed successfully!

I tried to resolve this problem by wandering through different forums. However, no luck yet! Can anybody help me resolve this problem and get my Windows Installer back on track?


By the way, I did the following:

Run cmd.exe with administrative previlliges and type sfc /scannow

Following is the output I received -
= = = = = = = = = = = = = = = = = = = = = = = = == = = = = = = = = =
Microsoft Windows [Version 6.0.6002]
Copyright (c) 2006 Microsoft Corporation. All rights reserved.

C:\Windows\system32>sfc/scannow

Beginning system scan. This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.
Windows Resource Protection found corrupt files but was unable to fix some of them.
Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For example
C:\Windows\Logs\CBS\CBS.log

C:\Windows\system32>

= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =
Does anyone have any idea of what's going wrong here? Do I have to fix the corruption to make this installation happen?

Please help me resolve this issue.

Thanks,
Shirish

Have you tried running it more than once, It might not be able to fix them all at once.

richc46 and derekimo,

Thanks for your time and replies.

First of all, the windows installer says that this one is an important update. However, I don't know if I already have it. (I doubt that). Anyways, I have tried installing this one multiple times over the last couple of weeks and run into the error code 652 each time.

Any thoughts?

Thanks,
Shirish

I'm Sorry if I wasn't clearer or maybe I was, but I was talking about the sfc /scannow not being able to fix all at once. therefore it might need to be run more than once.

Uninstall completely Silverlight and reinstall it again.If still no result prepare report from SFC command:

run cmd.exe with administrative previlliges (right click on cmd.exe) nad type:

findstr /c:"[SR]" %windir%\logs\cbs\cbs.log >%userprofile%\Desktop\sfcdetails.txt

On your desktop appear sfcdeteails.txt file,next run Readiness Tool Description of the System Update Readiness Tool for Windows Vista, for Windows Server 2008, for Windows 7, and for Windows Server 2008 R2

Readiness Tool create report -CheckSur.log file in C:\Windows\Logs\CBS folder.Both sfcdetails.txt and CheckSur.log files attache to post.

Hi,

Go to, download and install the Windows Installer Clean-up Tool from here: http://download.microsoft.com/downlo...bd/msicuu2.exe and remove Microsoft Silverlight if you cannot uninstall it normally. Then retry the update or download Silverlight from the Official Microsoft Silverlight site here: Get Started : The Official Microsoft Silverlight Site and click Windows Runtime on the right.

Thanks for your time and suggestion. When I tried to install the Windows Installer Clean-up Tool, I got an error message: "Error 1500. Another installation is in progress. You must complete that installation before continuing this one. " !!

Any thoughts?

Thanks,
Shirish
