Just purchased a PC from a business which closed and sold all of its office supplies. I purchased the tower, flat-screened monitor, mouse, speakers and keyboard for what I call a little of nothing. Anyways, when I purchased this system the owner told me that I shouldn't have any problems. Also that there were no passwords unless it would be for the log in screen which I have taken care of and that part works perfectly. However, there are a few programs such as Trend Micro/Client Server Security Agent which when I try to delete it at the add/remove programs list it will not delete. Also, when I try to install the game Command & Conquer: Generals on this PC it gives me the following error -- Error 1603 during installation. Consult Windows Installer Help (Msi.chm) or MSDN for more information. There are other things that I have caught my attention but when I began a list in my head I realized that I just needed to get some help to give it a good clean sweep. If this doesn't work then I am debating on either calling the guy back or dumping the PC and just reinstalling the operating system. My operating system is Windows XP Professional by the way. I am running a Dell desktop system with Windows XP Professional Version 2002 Service Pack 3 and I do have admin rights. Also the PC has Intel Pentium 4 CPU 2.80 GHz 2.79GHz 504 MB of RAM. My system restore is on. Any help would be appreciated.
