June 2026: Aurora-Viewer, Free Primavera P6 XER File Viewer UPDATE

The Free Aurora-Viewer for XER files has been expanded with more capabilities. Thank you for the feedback!

This 2026-June release adds new schedule analysis, reporting capabilities, and more.

Highlights include:

• Utilities > Run Logic Checks
  • Runs a set of model analysis methods to catch common modeling problems.
• Utilities > Find Redundant Constraints
  • Shows redundant constraints.
• Reports > DCMA Report
  • Shows a subset of the 14 DCMA audits.
• Reports > Critical Path Predecessor Chart
  • Shows how many tasks on the critical path have a certain number of predecessors. This provides insight into how much of the longest path through the network is susceptible to integration risk / merge bias. Integration risk / merge bias is the risk that one or more tasks feeding a successor task will be late, thereby delaying the start of the successor task. Since the successor task is part of the critical path, then any predecessor delay will directly affect the end date of the project.
• File > Open XER (if includes Greek characters)
  • Users can now open XER files where the text includes Greek characters. When such files are imported, the text, e.g., activity names, will be displayed correctly across the Aurora UI.

Aurora-Viewer is a free Windows-based tool for viewing Primavera P6 XER schedules—based on the Aurora intelligent scheduling and project management software.
