I have a HP Compaq 6820s. My operating system is Windows Vista Home Basic (32-bit). I am trying to install Windows Vista service pack 1 on the system. I downloaded the the SP 1 installation program from the microsoft website and saved it to my desktop. When I try and install it I get the following error message:
error code: 0x800B0100
I followed the link in the error message to the microsoft site and downloaded and ran their The System Update Readiness Tool. Restarted my system and tried to run the SP 1 program but got the same error message.
I then disabled my anti-virus and again tried to run the SP 1 program with the same results.
Ultimately I want to install SP 2 but I believe that I have to install SP 1 first.
Can anyone help with this problem?
