Can't install programs, SFC Cannot repair corrupt file

Here is the CBS.log:

Code:

How can I fix that?

Thank you.

Thanks for the reply.

I edited the registry and made it use a previous version of TrustedInstaller... so far so good, I was able to install a program.


I won't stress about the corrupt file, as long as everything appears to work. Otherwise I'll be back.
