How to determine whether you have a damaged presentation

There are several ways to determine whether you have a damaged presentation. You can try to open the file on another computer that has PowerPoint installed to see whether the unexpected behavior occurs on the other computer. You can try to create a new file in PowerPoint and see whether the unexpected behavior occurs with the new file. This section describes how to use existing presentations and how to create a new file in PowerPoint to determine whether the presentations have the same behavior.

Method 1: Open an existing presentation

  1. On the File menu, select Open.
    • In PowerPoint 2007 select the Microsoft Office Button.
  2. Select a different presentation, and then select Open.

If this presentation opens and seems to be undamaged, go to Method 3 in this section. Otherwise, go to Method 2 to create a new presentation.

Method 2: Create a new presentation

Step 1: Create the presentation
  1. On the File menu, select New, and then Welcome to PowerPoint (or Introducing PowerPoint 2010).
    • In PowerPoint 2007, select Installed Templates, and then select Introducing PowerPoint 2007.
  2. Select Create. This process creates a presentation that is based on the template.
  3. On the File menu, select Save.
    • In PowerPoint 2007 select the Microsoft Office Button, and then select Save.
  4. Type a name for the presentation, and then select Save.
  5. Exit PowerPoint.
Step 2: Open the new presentation
  1. On the File menu, select Open.
    • In PowerPoint 2007 select the Microsoft Office Button, and then select Open.
  2. Select the new presentation, and then select Open.

If you cannot open or save the new presentation, go to Method 3.

If you cannot create a new presentation, PowerPoint may be damaged and a repair should be initiated. (See Method 3, Part 2 below.)

Method 3: General troubleshooting

Windows 10, Windows 8.1, Windows 8, and Windows 7

  4. On the Services tab, select the Hide all Microsoft services check box, and then select Disable all.
