Hi jdc and thanks for posting back. I was just coming back here to say that I left out an important part of my thread. Some words to the effect that the viewer does not support the type file(s) I am opening. AND with your prompting, these appear to be PPS. I think I recall that the free version of PPS for windows 7 is 7. The thought just occurs to me that since my recent problems with Boot Disk, I may no longer have PPS installed.
