Project files saved in a version earlier than Microsoft Project 2000 can't be opened

Aspose generated MPP file shows the error message “Project files saved in a version earlier than Microsoft Project 2000 can’t be opened”. However I used 2013 version of the MPP template. Now, I don’t understand why do I receive the below error message when I click on save MPP file on the generated MPP file.


I have attached the mpp template and generated mpp for your reference. Please Help me on this.

Hi Sanjay,

Thank you for your inquiry.

I have investigated this issue at my end by using the template MPP file and re-saving it to disc using the latest version of Aspose,Tasks for .NET 7.3.0. The saved file opens fine in Microsoft Project and doesn’t give any error message if saved back. Could you please test it with this latest version and let us know your feedback? If the issue persists, we’ll also be in need of your sample code that generates the problematic output MPP file. We’ll look into it for assisting you further in this regard.

Thanks, that worked. :slight_smile:
