Updating QPR ProcessAnalyzer Server

This page contains instructions how to update an existing Windows installation to a newer QPR ProcessAnalyzer version.

Starting with QPR ProcessAnalyzer 2026.1, the platform now uses .NET 10 instead of .NET 8. If you are upgrading from a version earlier than 2026.1, you must install .NET 10 before completing the update. While both .NET versions can run side by side, .NET 8 does not need to be removed immediately. However, for security reasons, it is strongly recommended that .NET 8 be uninstalled as soon as possible after the upgrade. Download .NET 10: https://dotnet.microsoft.com/en-us/download/dotnet/10.0. For QPR ProcessAnalyzer Server, install the ASP.NET Core Runtime (hosting bundle).
