One rather abstract idea would be to install the software to see all product information as well as files copied to the drive and then manually delete the main registry key found in the system registry. Then you follow that up by rebooting and going online to see if the problem persists. With the reboot the registry values won't be there to load the software or whatever is causing the interference.
Software disks have their own product id number and key where the prompt for disk is usually to verfiy the product itself. You'll find that often on just about any type of software and have to expect it. The idea is to keep the software side from loading including any IE windows that would normally be seen if any for an ad?
You have to be cautious whenever making any changes in the registry itself. The method when using the regedit command and opening up the edit tool is to go into the "HKEY_LOCAL_MACHINE>SOFTWARE>" and look for the Hewlett-Packard main key and highlight it to see that removed. Once highlighted go to the menu bar and select the edit menu and scroll down to the delete option. The software is probably 98-ME not XP orientated explaining the problems being seen.
