Vista Trustedinstaller Missing

Hallo, I have problems with a notebook of a client of mine. Since October 2008 there are no updates, error 80070424.

How do I restore trusted installer when it is missing. Trusted Installer missing. I do not have a copy of TrustedInstaller.exe available to me. What is TrustedInstaller.exe process? Why does Windows Modules Installer service use high processor power and make my system slow? Can I disable TrustedInstaller.exe?

The same with sp2, trying to install from a cd. (missing service) I tried a lot of things (registering wuaueng.dll by hand, rename the catroot2-folder, installer-update from microsoft), but found out now: the trustedinstaller service is not there. The trustedinstaller.exe was missing in the servicing directory, but i managed to get it there.

But there must be more errors, since the service does not start. The files in the windows-system-directories belong to an owner 'unknown account' Is there a way to get back this service trustedinstaller. It would be a lot of work, setting up the notebook again.

Hello Ingo: 80070424 usually means that the BITS service (required by Windows Update) is not running. Have a look at this article. It may be relevant to your problem.

The services 'bits' and 'windows update' are running and can be stopped and started without any problem. I tried to install the microsoft update agent (Version 3), but it said unrecoverable error and stopped. George Morris Earn As You Learn Program: Software Free Download there.

I checked for malware, but found no evidence for it. I am nearly 100 per cent sure that the whole problem comes from the missing (or wrong) trustedInstaller-Service/Group.

This would also cover the problem with the microsoft update agent. On the files in the system32-directory, if you look-up the security-tab, there is no entry for trustedInstaller, but beside the entries for administator and user there is an unknown account (S-1-50.). I think, this was the TrustedInstaller. Many thanks again Ingo '??�?l' schrieb im Newsbeitrag news:1AF8BBA6-A837-412D-9206-F9BE50DC65BC@microsoft.com.>Let us know how it works �ut.
