Cannot install Windows 7 SP1, Error 800B0100, TRUST_E_NOSIGNATURE

I have scoured the internet and tried EVERYTHING to fix this problem.  Nothing I do works.

Tried SFC /scannow - did not work.
Tried Checksur - did not work.
Tried to fix activation.  Fixing and resetting activation worked, but still can't update to SP1
Tried cleanboot - did not work.
Tried various FixIt tools.  Nada, zip, ready to throw a grenade at this computer :-)

I have been through every thread on Sevenforums, technet, our own EE, phoned a friend, held a rubber chicken over the PC while chanting the Jedi Oath and standing on my held while grabbing my left pinky toe.  NOTHING WORKS! lol

I've attached a lot of logs.  Any thoughts appreciated.

Just thought I'd add to the fun of how I got here.  

So I'm systems administrator who is the victim of the Boss' wife thinking she can do my job, and has installed every antivirus program known to man, because everything "must be a veye-russs" *SMH*

My problems started when the user kept losing his ability to browse.  I fixed that with a script I created called "stop whining"

@echo off
echo "Unstucking...system sticky-goo...."
netsh int ip reset resetlog.txt
echo "System is unstuck"
echo "Unfortunately a reboot is required to complete"
echo "Stop whining, save your work and press enter to restart"
shutdown /r

Well...then I had the problem where the system would reboot, show the desktop wallpaper (a picture of the user's nice family *cough*, the desktop icons would appear, then disappear.  I'd start task manager and manually start explorer.exe.  Now there were two of them.  I killed the one with the smaller file size.  Then that problem magically went away.  I have no idea why it started, or why it stopped.

Next I ran various version of malwarebytes, avast, angry leprechauns fixing your  Mostly I found PUPs and removed them.  

The last problem is this stupid windows 7 service pack 1 issue where no matter what I've uninstalled, refreshed, etc, it just won't take.

Sounds like a Factory Restore is in order...  I'm doing that right now with two Windows 7 laptops.  But I didn't have to save anything, complete delete, format and restore.

"You can only do a repair install with the same edition Windows 7 installation disc for the same edition of Windows 7 that you have installed."

But hey.  I love your optimism lol

I would try a Repair Install before reinstalling. I would first uninstall ALL Antivirus software. Use care without A/V. Then run the Repair Install. Then on a good computer, download SP1 offline install file and see if you can install. If you do, pick ONE Antivirus and go with that.

If not, then a fresh install is in order.

I just did a factory restore on two HP G62 laptops.  One of them installed Win 7 SP1 without any problems.  The other one failed 3 times before I found a Microsoft FixIt thru the Help pages that finally allowed me to install it.  I had a different error number, something like 80072002.
after the factory restore, it seems you'll need to educate your customer a bit (lol) - or after a month or 2 you'll likely have the same problem
I am not sure I understand your message in http:#a40833729

Guys... All joking aside, let's show the world we're "experts" exchanging.  My 5 year old sister can reinstall windows.  Actually she can code, so maybe she's not the best example lol.  But seriously, the logs show what is wrong.  I have the luxury of time.  Additionally there are proprietary programs for which we no longer have a copy, and couldn't be reinstalled.  If I could have just done a repair install, or wipe and reinstall, I would have done it already.  I came here for the collaboration.  One of the disadvantages of being the *only* IT guy in the shop is that I don't have the benefit of a team to look at a problem together with.  Plus I'm not awarding anyone points for telling me to reinstall windows lol.

From everything I've looked at in the logs, it seems to be a problem with the activation tokens.  I tried to rebuild them, but it didn't help.  

Today what I'm going to do is uninstall the one remaining anti virus program (Norton's 360), then manually delete from the registry the remnants of other AV programs that were installed.

If that doesn't work, then I'm going to try doing a windows update reset, wipe out all the updates, and rebuild the update database from the beginning.

Let's take this opportunity to understand what is really failing under the hood of this machine.  We will all be better techs for it.
JohnBusiness Consultant (Owner)Commented:
@dgronbach - Why are you making fun of us?

We (I) have looked at ALL you have done and nothing has worked. We have already asked to remove Anti Virus applications as a start in the repairs. You said you tried the FixIt software to repair SP1 install.

When I see computers in this sad state, I save MUCH time by backing and doing a fresh install.

We are NOT juveniles taking the easy road out.

You misunderstand my humor.  Don't take offense.  Reset.
JohnBusiness Consultant (Owner)Commented:
Additionally there are proprietary programs for which we no longer have a copy,  

More evidence of a sorry state. We really are trying to help, and for the most part here, we know what we are doing.
dgronbachAuthor Commented:
I know.  Yes, the system is in a sorry state.  In this case I'm not looking to save time.  I'm looking to chase this problem down to root cause and solution.
" Additionally there are proprietary programs for which we no longer have a copy, and couldn't be reinstalled.  If I could have just done a repair install, or wipe and reinstall, I would have done it already.  "

Having programs for which you no longer have a copy is exactly the reason to consider a Repair Install.  It should not affect installed programs ( or personal data).

Did you try or find the Microsoft Fixit I mentioned?
dgronbachAuthor Commented:
These are the fixits I have tried:

I wonder what would happen if I just deleted these MUM and CAT files...

Unavailable repair files:
Dave BaldwinFixer of ProblemsCommented:
I can't seem to find the FixIt I used.  I 'Ran' it instead of downloading it so apparently it's gone.
JohnBusiness Consultant (Owner)Commented:
FixIt's go away if they have issues or replaced by newer ones.

I'm talking about one from yesterday...

Poor Neil.

"An examination of your System Information file reveals that you have a corrupted operating system, which in my view you are not going to be able to satisfactorily repair. You are going to have to reinstall Windows 7. Before you do so it would be sensible to see if there are any problems with your internal hard drive and RAM. Something started the file corruption and it advisable to confirm that these two items of hardware are not defective before reinstalling Windows."

There has to be an actual reason for this failure and a manual way to fix it without reinstalling.  Reinstalling fixes *everything* even that which does not need to be fixed.  I'd like to really drill down into the weeds, identify the root cause, and fix this individual problem.
dgronbachAuthor Commented:
Instead of deleting, there are some threads which suggest copying these MUM and CBS files from a working computer with an identical OS.
JohnBusiness Consultant (Owner)Commented:
You may wish to check if you can copy the files. I have a properly working Windows 7 machine (no updates failed or pending) and I do not see the files on my machine. They disappear apparently after successful updates.
Dave BaldwinFixer of ProblemsCommented:
And when you get SP1 installed, at least when I did, the next day there are only 213 updates to install.
JohnBusiness Consultant (Owner)Commented:
Did you find the CAT and MUM files?

I finally found them in c:\windows\servicing\pacakges
dgronbachAuthor Commented:
I know where they are.  But I didn't do any work on this today.  I'll resume Friday.

There has to be an actual reason for this failure and a manual way to fix it without reinstalling.  Reinstalling fixes *everything* even that which does not need to be fixed.   Consider the time you've spent already. And it could be a cascade of problems. Each of them contributing to the failure.  Investigating and finding each of these little problems which by themselves don't present a noticeable problem.  

If you had a backup that worked then you wouldn't be in this quandary. Start the restore go to lunch.. come back in an hour to a working machine. Yes, hindsight has 20/20 vision.
have you tried the instructions from

The above problem was caused by incorrect permissions. Sysinternals Procmon was also mentioned to find the offending update catalog file and how to fix it once found.
Rather than delete I'd rename the folder names first. If it doesn't work then you can rename them back

" Consider the time you've spent already."
In this instance, I have the luxury of time.  So I'm taking advantage of it.  My goal is to flesh out the root cause of this problem and fix it.  The system is no unusable.  These are things that only bother systems administrators :-)

"And it could be a cascade of problems. Each of them contributing to the failure."
You got that right!  What a fuster cluck!

"If you had a backup that worked then you wouldn't be in this quandary. Start the restore go to lunch.. come back in an hour to a working machine. Yes, hindsight has 20/20 vision."

My hindsight doesn't extend past my hire date.  I'm like Obama - taking the blame for and trying to fix the mess the GWB left behind.

"have you tried the instructions from..."
I had them printed, sitting at the user's desk, plugging away before I ever came to EE.  But that is a great article and I think you're right that it's a fuxored set of permissions somewhere.  And yeah, I mean "rename" not delete.  But at this point, if it doesn't work, then I will feel like I've exhausted every conceivable troubleshooting effort to ferret out the root cause, and I will come back with a blow torch, a flam thrower and a new Windows 7 Professional Disk.  This time it *will* have a backup.  This is what happens when you have non-sysadmins thinking they can do our jobs.
dgronbachAuthor Commented:
Today I tried copying the manifest .cat and .mum files from a working computer, then re-ran the CheckSUR...same error.  

Ok folks.  I've filled the fuel tank on the flame thrower and lit the fuse.  My attentions are now turned to backup, wipe and reinstall.  I'm not even going to bother with a repair install.  There is some much broken in this system, I don't think repair would really know what to repair.

Before I throw in the towel, as I've repeatedly said, I have the luxury of time since the user can still check his email and browse the web.  Really. We do all this work so our users can post updates to facebook. LOL
Is there *anything* else, no matter how ridiculous, someone can think of to find the root cause and FIX this system?  (Assuming "NO, now go away" is the answer).

How do you want me to distribute the points?
JohnBusiness Consultant (Owner)Commented:
We have asked you to consider reinstalling Windows, so split the points amongst the key answers here.

Grade The Solution: Boxed into a corner.  I don't wanna grade the solution.  I don't wanna lol.  I'm giving the solution a Grade of C because it's lame.  Why is it everything we do in this arena ultimately comes back to "reinstall the OS"?

Thank you, fellow experts, for your time and attention towards helping me find a root cause.  You guys get a Grade of A.
Dave BaldwinFixer of ProblemsCommented:
Because it's too dang complicated and interdependent.  Once it starts going 'off the rails', it can be impossible to put it back on the track.
i spent once 2 weeks on such a problem, even copied folders from fresh installs - to no avail
it is as Dave says : it's too dang complicated and interdependent
remember there are hundreds of thousands of OS and driver files, which are interacting

i sure would like there was another good method -but up to now, i don't know one
