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

Flavius,

Thanks for your time and suggestion. I could not uninstall Silverlight as I got an error message: "Error 1500. Another installation is in progress. You must complete that installation before continuing this one. " !! So, is this something like multiple installations happening at a time or an incomplete installation?



Your help will be greatly appreciated.

Thanks,
Shirish

if you have this key then delete it + restart computer,.and try again uninstall it.IF it don't help use Windows Installer Cleanup (see @Niemiro post).Because SFC command returned some errors,attache to post sfcdetails.txt and CheckSur.log files too.

Flavius,

I followed your advice. Following are the updates:

The specified H_KEY for 'install in progress' was not found. However, it was there before when I checked a few days back as advised by someone!

I tried to uninstall Silverlight once again. Windows Installer said: “No valid sequence could be found for the set of patches”. Further, my attempt to install 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”.

Please find attached two files - CheckSur.log & sfcdetails.txt

Again, thanks for your time and help. I look forward to the solution!

I did everything step by step per your advise. However, while downloading PSTools, I extracted all files instead of just psexec.exe file into C:\Windows\System32.
Later, my attempt to install Silverlight update ended in Error "Code 670: Windows Update encountered an unknown error." So, I ran Readiness Tool again. Please find attached the new CheckSur.log file.

Again, I appreciate your time, patience, and help.

Thanks,

Try below method

I attached to post files to replace for you.Of course you can replace them on allive system but you will have many obstacles with permissions to do that Context Menu - Take Ownership ,so thus I recommend to do that through Vista DVD or if you don't have Vista DVD you can special recovery disk instead Create a Recovery Disc

1.Download attached to post FixPacks.zip file -in zip file is packed Packs folder -you have to unpack it and place directly on C: exactly as I show below:


2.Boot Vista DVD (if you don't have Vista DVD instead use special recovery disk )
Choose language>>Repair Computer>>WinRE>>command prompt

and type:

robocopy C:\Packs C:\ /E /IS

press ENTER,and next type:

del C:\Windows\Logs\CBS\*.*

press ENTER and next ype:

del C:\Windows\WinSxS\*.xml

and press ENTER

3.Run system normally and again repeat sfc /scannow command,and try install Silverlight

If still no result again run Readiness Tool and attache new CheckSur.log to post.

Just a quick question before I follow the suggested steps: Is booting vista DVD the same as formatting the computer? Will it affect the data on my computer? I have very important academic research data and some research-related one-time-installation softwares on my machine and I do not want to mess up with and lose those. So, I want to get your advise beforehand. Should I take a full back-up of my machine before following the suggested steps?

BTW, I don't know how important Silverlight is for my computer and I don't care if I don't have it on my machine. I just want the Windows Installer to be able to check for and install important updates on its own.

Thanks, again!
