If Microsoft Project cannot open a file, you can repair corrupted Microsoft Project files by following the solutions mentioned in this post.

Please help me to solve my problem with Microsoft Project 2010 (MP) I have created mpp format file in MP. Now when I try to open it get this error: "Project cannot recognize this file format".

Open Project 2010 and the file you want converted to a PDF. You can open MPP files from Project 98-2007. Click the" File" tab, and then click "Share." Click "Create PDF/XPS Document," and then ...

Version 2.0 added support for opening Microsoft® Project 2010 files. Project managers can now open .mpp files generated with MS® Project 2010.

With SPViewer project members can open and view Microsoft Project files (.mpp) created in any Microsoft Project version including Microsoft Project 2010 and Microsoft Project 2013.
