Hi Starbuck, I tried to install the printer again, with the same results and error messages. I then disabled the 'Interactive Services Detection' service, restarted, and tried to install the printer one more time. The install ended up freezing around the same time I usually receive the error message. I had to leave so I left it alone for a couple of hours and it was still frozen and unresponsive when I got back. I had to close it out using 'task manager'. I haven't contacted HP about the problem for a couple of reasons. One, I saw others say that when they contacted them they were told (whether true or not) it was a problem on Microsoft's end and that they couldn't help. Two I feel like if I explained what happened they would say something like "Well the printer was working fine until you got malware and did a system restore. Clearly its something you did wrong and its unrelated to our software". But I guess I probably should contact them just to see if they can offer any assistance. Also, I read the info in this link you posted: http://blogs.msdn.com/b/patricka/ar...eshooting-interactive-services-detection.aspx I had never noticed the drop down box that said 'show program details'. I clicked it on this time when I received the error message and it said C:Windows\System32\spoolsv.exe was the culprit. I then created a custom view in the 'event viewer' like the article said. It gave me a list of every time the error has occured. The first occurrence was 12-19-2012 if that helps you in any way. I also looked at the details for every time the error has occured. They are all the same and they all say: "Device or Application: C:\Windows\System32\spoolsv.exe. Message title: Microsoft Visual C++ Runtime Library". Does this mean that 'spoolsv.exe' is whats causing the problem? As far as digging deeper with other programs, I'm all for anything that you think could possibly help. Thanks!
