How to open old PowerPoint presentation files

If you have a very old PowerPoint presentation file, you wont be able to open it with PowerPoint. Here's How to open old PowerPoint presentation files..

A coworker told me he couldn’t open a couple of PowerPoint presentation files, because they are really old. He said he’s trying to open the presentations with Microsoft PowerPoint 2010 with no success. “How old are they?” I asked him. “Pretty old” he said. “Send it over” I told him.

Once I got the files, I realized they are really, really old. 1998 old. Yep.

I also tried to open them, thinking that every newer version of PowerPoint – newer than 1997 – is supposed to open older versions’ files. No luck. The files were created with Power Point 4.0 (Released 1993). When I tried to open the files, all I got was the following error:

PowerPoint can’t open the type of file represented by [filename]

PowerPoint can’t open the type of file represented by [filename]

  1. I have pre-2000 aircraft system CDs that didn’t work with PowerPoint Viewer. So I right clicked, chose Open With, and selected PowerPoint, the program. Using that the program ran OK.
