Corrupt Pptx files. Need to repair them. Please help!

[BallSteven2]

Hey guys, there is big mess over here.
Here I quote: I made some presentation files for promoting our new business. I showed them to my boss. She was quite happy with my work and asked me to send them to our clients. Next day I sent them to all our clients. In the evening time boss got some mails from those clients that the files are not opening. So she asked me to make them again.
I have no more time and it is certainly impossible to make those files again but there must be a solution for this situation. Please help. Your help will be surely appreciated.

Summary
You may experience unexpected behavior when you work with a Microsoft Office PowerPoint 2007 or PowerPoint 2010 presentation. This behavior may occur because the presentation is damaged. This article contains step-by-step methods to try that may help you partially restore or fully restore your presentation.
This article is intended for a beginning to intermediate computer user.
You may find it easier to follow the steps if you print this article first.
Symptoms of the problem
When you try to open or change a presentation that is damaged, you may experience the following symptoms:

• When you try to open a presentation, you receive one of the following error messages:
  This is not a PowerPoint Presentation
  PowerPoint cannot open the type of file represented by file_name.ppt
  Part of the file is missing.
• You receive the following types of error messages:
  General Protection Fault
  Illegal Instruction
  Invalid Page Fault
  Low system resources
  Out of memory

Methods to determine whether you have a damaged presentation
There are several ways to help determine whether you have a damaged presentation. You can try to open the file on another computer that has PowerPoint 2007 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. In PowerPoint 2007 click the Microsoft Office Button. In PowerPoint 2010 click the File menu and then click Open.
2. Click a different presentation, and then click Open.

If this presentation opens and appears 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. In PowerPoint 2007 click the Microsoft Office Button, and then click New. In PowerPoint 2010 click the File menu.
2. In PowerPoint 2007, click Installed Templates, and then click Introducing PowerPoint 2007. In PowerPoint 2010 click the File menu, click New, click Sample templates, click Introducing PowerPoint 2010.
3. Click Create. This process creates a presentation based on the template.
4. In PowerPoint 2007 click the Microsoft Office Button, and then click Save. In PowerPoint 2010 click the File menu and then click Save.
5. Type a name for the presentation, and then click Save.
6. Exit PowerPoint.

Step 2: Open the new presentation

1. In PowerPoint 2007 click the Microsoft Office Button, and then click Open. In PowerPoint 2010 click the File menu, and then click Open.
2. Click the new presentation, and then click 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 must be repaired.
Method 3: General troubleshooting
Windows 7, Windows 8/8.1, Windows 10
Part I
For the clean reboot, please follow the steps:

1. Log on to the computer by using an account that has administrator rights.

   Note This step lets Microsoft services continue to run. After you do a clean reboot, please check Office performance and resume normal startup.

Part II
Go to control panel, repair office programs (right-click it, select change), we suggest a quick repair first and online repair later.
Methods to try if you cannot open a presentation
Method 1: Drag the presentation to the PowerPoint program file icon
Windows 7

1. Click Start
   
   , and then click Documents, or Click Start and then search for Windows Explorer.
2. In the Address Bar, type %ProgramFiles(x86)%\Microsoft Office\Office12 (PowerPoint 2007), and then press ENTER. If you have PowerPoint 2010 installed type %ProgramFiles%\Microsoft Office\office14 (PowerPoint 2010 64 bit), or %ProgramFiles(x86)%\Microsoft Office\office14 (PowerPoint 2010 32 bit), and then press ENTER.
3. Locate the Powerpnt.exe icon in Windows Explorer.
4. Drag the damaged presentation icon from one window to the Powerpnt.exe icon in the other window.

Windows 8/8.1/10

1. Right click
   
   , and then click Run.
2. In the Open box, type C:\Program Files (x86)\Microsoft Office\Office12 (PowerPoint 2007). If you have PowerPoint 2010 installed type C:\Program Files\Microsoft Office\office14 (PowerPoint 2010 64 bit), or C:\Program Files(x86)\Microsoft Office\office14 (PowerPoint 2010 32 bit), and then press ENTER.
3. Click OK.
4. Locate the Powerpnt.exe icon in Windows Explorer.
5. Drag the damaged presentation icon from one window to the Powerpnt.exe icon in the other window.

PowerPoint will try to open the presentation. If PowerPoint does not open the presentation, go to method 2.
Method 2: Try to insert slides into a blank presentation
Step 1: Create a blank presentation

1. In PowerPoint 2007, click the Microsoft Office Button, and then click New. In PowerPoint 2010, click the File menu, and then click New.
2. Click Blank Presentation, and then click Create.
   
   This process creates a blank title slide. You can delete this slide later after you re-create the presentation.

Step 2: Insert the damaged presentation as slides

1. On the Home tab, click the arrow next to New slides in the Slides group, and then click Reuse Slides.
2. In the Reuse Slides task pane, click Browse. Click the damaged presentation, and then click Open.
3. Right-click one of the slides in the Reuse Slides task pane, and then click Insert All.
   
   If this operation is successful, all the slides from the damaged presentation, except the slide master, are inserted into the new presentation.
4. In PowerPoint 2007 click the Microsoft Office Button, and then click Save. In PowerPoint 2010 click the File menu, and then click Save.
5. Type a new name for the presentation, and then click Save.

Step 3: Apply the damaged presentation as a template
If the presentation does not look the way that you expect after you try these steps, try to apply the damaged presentation as a template. To do this, follow these steps:

1. In PowerPoint 2007 click the Microsoft Office Button, and then click Save as. In PowerPoint 2010 click the File menu, and then click Save as.
2. Type a new name for the presentation, and then click Save.
   
   This will make a backup copy of the restored presentation, in case the damaged presentation damages this new presentation.
3. On the Design tab, click More in the Themes group, and then click Browse for Themes.
4. Click the damaged presentation, and then click Apply. The slide master of the damaged presentation replaces the new slide master.

Note If you start to experience unexpected behavior after you follow these steps, the template may have damaged the presentation. In this case, use the backup copy to re-create the master slide.

If the backup copy of the new presentation exhibits the same damage or strange behavior as the original presentation, go to method 3.
Method 3: Try to open the temporary file version of the presentation
When you edit a presentation, PowerPoint creates a temporary copy of the file. This temporary file is named PPT ####.tmp. Occasionally, if there are issues with your presentation, the temp file will remain in the saved file location.

Note #### represents a random four-digit number.

This temporary file may reside in the same folder as the presentation save location. Alternatively, it may reside in the temporary file folder.
Rename the file, and then try to open the file in PowerPoint

1. Right-click the file, and then click Rename.
2. Change the old file name extension from .tmp to .pptx so that the file name resembles the following file name:
   PPT ####.pptx
3. Start PowerPoint.
4. In PowerPoint click the File menu, and then click Open.
5. Browse to the folder that contains the renamed file.
6. Try to open the file in PowerPoint.

Note More than one file may correspond to the temporary file that was created the last time that you saved the presentation. In this case, you may have to open each file to see whether one is the temporary copy of the presentation.

If there are no temporary files, or if the temporary files display the same kind of damage or strange behavior, go to method 4.
Method 4: Try to open the presentation in PowerPoint Viewer.
