PowerPoint has encountered errors and cannot open this file. Try opening another copy of the file. For example, if the file was sent to you in an e-mail message, have the person who sent the message send it again, and then try to open the file again. If you opened the file from a disk, try to open another copy of the file on a new disk.
The problem may be a file-format issue, or it may be a file-corruption issue that requires repair.
PowerPoint can't open the type of file represented by ...
PowerPoint 2007 and later versions are unable to open a presentation that has been saved as a PowerPoint 95 file. To fix this problem, you need to change the underlying format of the PowerPoint 95 file:
Open the file in PowerPoint 2003, 2002, 2000, or 97.
Choose File > Save As.
(Don't simply choose Save. Use Save As, because the file must be saved in a different format.)
In the Save as type box, choose Presentation (*.ppt). Then select Save.
Now that the file is in .ppt format, you can open it in PowerPoint 2007 or a newer version.
"PowerPoint could not open the file", or "No text converter"
If you get a message that says, "PowerPoint could not open the file" or "No text converter", you probably have a file-corruption problem. See Open a document after a file corruption for the repair steps.
