Best Practices for Your DevExpress Universal Trial

To make the most of your 30 days, follow these guidelines:

• Document your test cases before installing. Know which controls (Data Grid, Charts, Scheduler, Rich Text Editor) you need to verify.
• Use a virtual machine (VMware, Hyper-V, VirtualBox) for the trial. This allows you to snapshot a clean state before installation. If you need to re-test after a failure, revert the snapshot instead of reinstalling.
• Do not install on a production build server. The trial license is per-machine and should not be used in CI/CD pipelines unless explicitly allowed by DevExpress.
• Explore the Demos – The installer places sample projects under C:\Users\Public\Documents\DevExpress Demos 24.1\. These are invaluable for understanding real-world usage.
• Check the Version Compatibility Matrix – Ensure your trial version matches your project’s .NET target. DevExpress drops support for older frameworks over time.

Troubleshooting Checklist

• Visual Studio shows missing toolbox items: run DevExpress Toolbox setup (DevExpress → Toolbox Setup) or repair installation.
• Build errors referencing DevExpress assemblies: ensure project targets a supported .NET version and references the installed DevExpress assemblies (use NuGet or the installed toolbox templates).
• Licensing/activation errors: sign out/in in Product Manager or re-run activation steps; check firewall/proxy if activation fails.

Issue: Design-Time Errors (Visual Studio crashes or freezes)

Cause: Corrupted Visual Studio component cache or conflicts with other extensions. Fix: Run Visual Studio in Safe Mode (devenv /SafeMode) to disable third-party extensions. Then repair the DevExpress installation.
