July 2025: Aurora-Viewer, Free Primavera P6 XER File Viewer UPDATE

Our free Primavera P6 XER file viewer for Windows has been updated.

The most up-to-date version of the Viewer for XER files now:

• shows the Project Overview Report by default after the user imports a .xer file

This report has been updated to also include:

• a ‘minimum non-zero duration’ row within the ‘activity details’ section
• a ‘zero duration jobs not marked as milestone’ row within the ‘job types’ section
• a ‘calendars’ section

This version also supports even larger models, enabling you to open and explore more extensive Primavera P6 schedules with ease. Plus, we’ve enhanced the Project Overview report:

• Displays by default immediately after importing an XER file
• Adds a “minimum non-zero duration” row in ‘Activity Details’ section
• Includes a “zero duration jobs not marked as milestone” row in ‘Job Types’ section
• Features a brand-new Calendars section

Other Aurora-Viewer notable features include:

• Gantt Charts
• Tabular / spreadsheet view
• Single-element view

The installation includes a “videos” subfolder with demonstration videos. See the Single-Element-Display video to learn how to better navigate and understand your schedule.

The Aurora-Viewer can be accessed by heading over to the Aurora-Viewer page.

Simply download and then open or double-click the installer to install it.
