Hi,
The error you're encountering during the upgrade to Dynamics 365 Server version 9.1.39.04—specifically Error 2771: Upgrade of feature Tools has a missing component
—is typically related to inconsistencies in the Windows Installer database, often caused by missing or corrupted components from previous installations.
Here are a few steps that may help resolve the issue:
Repair Previous Installations: As you've already done with the Visual C++ Redistributables, ensure that all prerequisite components (especially older versions like VC++ 2008 and 2010) are properly installed and repaired. Sometimes the installer expects specific files or registry entries that may have been removed or altered.
Clean Up Installer Cache: Use tools like the Windows Installer CleanUp Utility (if still available) or manually clean up remnants of previous updates that might interfere with the current installation.
Check Component Table: The log mentions a missing component registered to the Tools
feature. This could be a leftover reference from a previous update. If possible, inspect the MSI database using tools like Orca to verify the presence of the component {A2B3F2B0-1407-9952-929C-B2F15C874C44}
in the Component table.
Reinstall the Previous Update: Try reinstalling or repairing the previous update (9.1.35.06) to restore any missing components before attempting the upgrade again.
Run Installer with Logging: Continue using detailed logging (/L*v
) during installation to capture all errors. This can help identify the exact step where the failure occurs.
Microsoft Support: If the issue persists, consider contacting Microsoft Support with your logs. This error may require a manual fix or patch from their side, especially if it's related to a corrupted update package [1].
Please verify if this helps you move forward with the upgrade.
Thanks and best regards,
Daniele
