User called me last night, can't get HP drivers to install for printer. 500 meg download for latest c6180 driver. PC says "computer must be restarted to delete some files, then setup will continue." and it won't pass that point. (that's not exact phrasing of the error, and I'm not on the system now)
Target machine is XP SP2. I upgraded to SP3. Fully patched. Ran malwarebytes, spybot, hijack this and turned off all startup entries. I noted that windows update also failed on optional printer driver updates for other printers installed on the machine. Went to printer server properties, removed all print drivers from system, deleted all printer ports. Made sure no services were marked disabled.
After 5 hours of fighting this I started to get desperate, and uninstalled anything that referenced HP in the machine at all. Still no cure.
I'm 6 hours into this and completely stumped. Google returns nothing applicable except unanswered requests for help on same topic.
