Thanks again for your reply. My HP Pavilion 6645C does not have a Windows 98SE installation disk. The operating system came with the computer and I have two CDs that constitute a "System Recovery" resource that enables me to restore all the system files if I need to. I've used this thing before, and it has a life of its own, so I don't want to mess with it.
So I put "cryptui.dll" in a Google search engine and clicked on the first link that came up. It took me to a site that allowed me to download it without having to unzip it. I copied the original cryptui.dll file to a floppy disk, then installed the new one (a few kb larger, by the way) into the Windows\System folder. I then went to a .jpg file and right clicked on it for the options. I clicked on "Properties" and it opened like a charm with no loud noise of complaint, error message, or freeze-up. Problem solved! My computer is happier and so am I. Thanks again,
