windows 7 sp1 error

Hi,

I am getting error code 800B0100 (TRUST_E_NOSIGNATURE) (No signature was present in the subject) when trying to update from Windows Update. I can not install Win7SP1 (KB976932) from the site.

I have looked on google searches about this, but i haven't found anything really helpfull.

I am not sure what to do now. I know a fair amount about computers, but i am by no means an expert, and this is beyond me. I will be very gratefull if someone has
fix for this.

Regards,

Andy.

Good day to you, Andy, and welcome to the Seven Forums!

Please can you run the System Update Readiness Tool for me: Description of the System Update Readiness Tool for Windows Vista, for Windows Server 2008, for Windows 7, and for Windows Server 2008 R2

And then please upload C:\Windows\Logs\CBS\CheckSUR.log.

Thanks a lot!

Richard

Hello Jacee.

No I am currently using kaspersky Internet Security 11.0.2.556.



Thanks

Hello Jacee,

I have all the other Windows critical updates downloaded and installed, service pack 1 is the only one i'm having an issue with.

I will try malwarebytes Anti-Malware and let you know how i get on.


Thanks

Hello Richard,

Thanks for your nice welcome to the windows seven forums.

I have enclosed the CheckSUR.log file you requested.

I hope it gives you some understanding as to what the problem might be.


Thanks

Hello Andy!

Well done on uploading that log file. It has shown me exactly what is wrong with your computer.

The 0x800B0100 error code actually means that a few files (nominally .cat files, although for reasons I shall only go into if you ask me to :), actually .mum and .manifest files as well) have become corrupt.

They are quite easy to fix. :)

However, I am currently at my work place, and cannot create the required fix right now.

If you could please give me just a few hours, I shall create a special fix for you, and then you can run it, and all being well, this error code will become error code 0, ERROR_SUCCESS. (yes, in the same way that 0x800B0100 becomes TRUST_E_NOSIGNATURE, 0 becomes ERROR_SUCCESS)

Please just stick with me for a few more hours!

Thanks a lot for your patience and understanding!

Richard

Hello again!

All done!

WARNING! This fix was created specifically for this user! If you are not this user, do not follow these instructions!
@arjt1973: Ignore the above :)

Download the attached .zip file. Inside it, will be two folders, Packages and Manifests.

Create these folders if they do not already exist: C:\Windows\Temp\CheckSur\Servicing\Packages\ and C:\Windows\Temp\CheckSur\winsxs\Manifests

Extract Packs.zip onto your Desktop. Please place the contents of my Desktop\Packages in C:\Windows\Temp\CheckSur\Servicing\Packages\ and my Desktop\Manifests in C:\Windows\Temp\CheckSur\winsxs\Manifests.

DO NOT place the .zip file in that folder, or the folders themselves. Make sure that a lot of files are in each of those Checksur folder.

Re-run the System Update Readiness Tool, and get me another copy of C:\Windows\Logs\CBS\CheckSUR.log.

Also, please retest Windows Updates (with fingers slightly crossed, no matter how much we both know that that won't help! lol.)

Thanks!

Richard

Hello Richard,

I will download the zip file create the folders (if i don't have them) and copy the files to the folders and hopefully tell you some good news.

I will also Re-run the System Update Readiness Tool and upload you a copy of the CheckSUR.log.

Give me a little time and i'll get back to you with the results.

Thanks

Andy.
