How To Fix Powerpoint Can’T Read

Encountering the ‘PowerPoint Can’t Read’ error message can be disconcerting, especially if you’re in the middle of preparing for an important presentation. Thankfully, this is a problem that can be fixed. In this blog post, we will guide you step by step on how to resolve this issue.

Reasons for the ‘PowerPoint Can’t Read’ Error

Before we get into the solutions, it’s important to understand why this error can occur. There are several potential reasons:

  • The PowerPoint file may be corrupt.
  • There might be an issue with the software.
  • Your computer’s system may not support the file’s format.

Solution 1: Try Opening the File in a Different Format

The first solution to try is to open the file in a different format. For instance, if you’re trying to open a .ppt file, try saving it as a .pptx file instead.

Here’s how:

Right-click on the file > Choose Save As > Select .pptx from the dropdown menu > Click Save.

Solution 2: Use PowerPoint’s Open and Repair Tool

If changing the file format doesn’t work, you can use PowerPoint’s built-in Open and Repair tool.

Here’s how:

Open PowerPoint > Click on File > Choose Open > Select the problematic file > Instead of clicking the Open button, click on the arrow next to it and choose Open and Repair.

Solution 3: Install the Latest Office Updates

Another potential solution is to install the latest updates for your Office suite. This can fix any bugs or issues with PowerPoint that may be preventing your file from opening.

Here’s how:

Open any Office application > Click on File > Select Account > Under Product Information, click on Update Options > Choose Update Now.

Office.Application app = new Office.Application();
Office.FileDialog dialog = app.get_FileDialog(MsoFileDialogType.msoFileDialogOpen);
dialog.AllowMultiSelect = false;
int result = dialog.Show();
if (result == -1)
string filename = dialog.SelectedItems.Item(1).Path;
Office.Presentation presentation = app.Presentations.Open(filename, MsoTriState.msoTrue, MsoTriState.msoFalse, MsoTriState.msoFalse);
presentation.SaveAs(filename + “.pptx”, PowerPoint.PpSaveAsFileType.ppSaveAsDefault, MsoTriState.msoTrue);

This piece of code will save the PowerPoint presentation in .pptx format, which might help to resolve the error.


Experiencing ‘PowerPoint Can’t Read’ error can be frustrating, but with the straightforward solutions outlined above, you can get back to work in no time. Always remember to keep your software updated and to regularly save and back up your work to prevent file corruption.
