I have 15 page .pptx format presentation in PowerPoint 2013. When i try to open the file i recieve the following error message:
The file cannot be opened
I need to open it It is very important p

Does anyone have any ideas? how to repair .pptx file?

Best Regards

These steps are useless((

RESOLUTION: Right-click on the PPTx file name and select PROPERTIES. On this dialogue box, you will see a button marked UNBLOCK, click on this and then press OK. If it useless upload your file here You must login or register to view this content. That's it. Now the file will open.

Hope this solution helps.
