Fixing ?there Was An Error…? Error While Opening Ppt File

Those who create PowerPoint presentations, understand how much hard work and creativity is involved in creating a single presentation. However, if your presentation gets corrupted due to some logical or physical damage, all the hard work can go in vain. Under such circumstances, your PPT or PPTX file can not be opened and you encounter an error message. This message symbolizes that your file is corrupt and the data saved in it can not be accessed. To easily surpass such corruption scenarios, you need to access the file by restoring it from an adequate backup. But, in case the backup of that file is missing or deleted, then the only option you have, is to repair the corrupt file. For comprehensive repair of any logically corrupted PowerPoint presentation, you need to use an effective PowerPoint Recovery software.

Consider a practical case, where you encounter the below error message while trying to open your PowerPoint presentation:

?There was an error accessing file c:/xxxx?

The same error message pops up every time you try to open the PPT file. The data saved in the PPT file becomes inaccessible after the above error message appears.

Logical corruption of a PPT file due to improper system shutdown, application malfunction, and virus infection.

To resolve the above error message and to access the data saved in the PPT file, you need to:

Open PowerPoint, select File Option, and mouse down to your latest accessed presentations.
Save the file with a new name.
Open PowerPoint select Insert option, and mouse down to ‘Slides from files’ option. Click ‘Browse’ on the ‘Find Presentation’ tab and select the corrupt file. The step allows you to view all the slides in the presentation.
Restore the file from an updated backup.

However, if the above measures fail to resolve your issue, then you will need to use an effective PPT Repair software. A PowerPoint Recovery tool repairs and restores corrupt PPT and PPTX files by incorporating powerful repair algorithms.
