Laptop downloads and installs 32 bit files OK but stops- after starting- the 64 bit ones with the error message 800BO100. Running Windows 7 and wanting to install SP1. Any ideas? Thanks

800BO100 Usually relates to your firewall blocking the update.

Try disabling the firewall while you download the update.

Fruit Bat /\0/\ Thanks for your response. Tried shutting down virus and firewall programs without success. No joy from Microsoft help either.

Maybe have a look at this and download the Windows 64bit version.

It also gives the error code as.

0x800B0100 TRUSTENOSIGNATURE No signature was present in the subject.

PEG007 - If it is any consolation I have made several attempts to download/install SP1 using every method possible. I downloaded and run the System Update Readiness Tool (for 64bit) - disabled Firewall/Anti Virus but it made no difference - SP1 gets to 99% and fails. Same error code as you get.

My opinion is that it is because most of the updates contained withing SP1 are already downloaded and installed so I have no plans to make any further attempts.

PC is flying at the moment so I am no longer concerned with SP1 - the only thing is that it doesn't show up in Computer/Properties.
