[e07723]

I'm trying to install Service pack 1 and its coming up with this error:

Trust_E_NOSIGNATURE(0X800b0100)

I've downloaded the System Update Readiness Tool I just need someone to decipher the log. I would greatly apreciate it.

Hello and welcome to the Seven Forums!

Please can you upload for me C:\Windows\Logs\CBS\CheckSUR.persist.log, or otherwise copy and paste it in its entirety here, and then I shall analyse it.

Thanks a lot!
