You should open up the show through the program, not by opening the show from
the file. Once it is opened you can then resave it as a ppt. file. Hope
this helps

I assume that's a question. Either change the name of the file so it ends
in .ppt, not .pps, or open PowerPoint and choose Open from the File menu to
open the file. Now choose Save As from the File menu and pick PowerPoint
Presentation (*.ppt) as the Save as type.
