Windows Modular Installer

alzan135 · 06 Jun 2014

For a month now i have been having problems with Windows update not working. I have been getting error 80080005 after a lot of searching i think the problem is that something (Avast or Advanced System Care ?) has deleted a file in the windows registry and Windows Modular Installer is no longer working.

If i try restarting it i get an error 126 I have tried a number of solutions including adding a new registry key but nothing has worked. Now to add to the fun windows will not let me install a new printer driver. I am thinking now of doing a fresh install of Windows but before i do a couple of questions.

Any new suggestion on getting Windows Modular Installer working again. Windows works fine otherwise

I have 2 HDDs and i have Windows on one HDD whats the best way to do a fresh reinstall windows

Hi there ... Your System is completely messed up You could try a Restore point before things went pear shape .. But my guess is you do not have any ..So first thing to do is to Uninstall Advanced System Care as i am sure it has a lot to do with your problems ... Then you might try a Repair and Install ...

Repair Install

Have a look at these threads/topics:

Error 126: cannot start service - Windows Modules Installer

Error message when you start the Windows Modules Installer service (TrustedInstaller): "System Error 126: The specific module could not be found"

Take Ownership of file

TrustedInstaller - Restore as Owner

On a side note I would remove Advanced System care by IOBit on general principles alone.

(YMMV)
2nd Edit: I suggest a full malware scan with at least 2 programs; your AV (Avast) & Malwarebytes Anti Malware followed by a scan using Free Virus Scan | Online Virus Scanner from ESET

Thanks for the replies i have tried what is suggested but noting worked. So i suppose its a format and reinstall.

Do i need to set my PC to boot from the Windows DVD

The link about IOBIT was definatly an eye opener.

You did try the repair install? that should have given you a pristine registry.

Yes, Iobit stuff is very troublesome.

I did try the repair install. But a soon as i start it windows starts to check for updates but never gets past the looking for update screen. As windows update is broken

There does not seem to be a way to stop it looking for updates

I also then would suggest a full clean install. Back up all your personal data to some external device first.
