Regarding those errors during downloading the downloads, use the instructions from the following Downloads Fail and Security Warnings Appear after Installing Service Pack 2 for Windows XP page.

I have a new HP computer with the Windows SP2 installed. Have an HP 932C Printer and an HP Scanjet 3300C - having problems with both as far as installation. I've contacted HP several times and nothing has worked. When trying to download new CD for Scanner, get an error message about "digital signature". Had Windows ME before and had no problems - anyone have any suggestions? Thanks.
