Addins manager in Revit

Problem:

Users experience conflicts or slow startups in Revit caused by multiple add-ins loading simultaneously, making it difficult to identify and disable the problematic extensions quickly.

Solution:

1. Open the Add-Ins Manager

   • In Revit 2025.3 or later, go to Manage Extensions Add-Ins Manager.
   • Or launch the standalone tool:
     • Press the Windows key, type “Revit Add-Ins Manager,” and select it.
     • Or browse to %ProgramFiles%\Autodesk\Revit 2025\AddInsManager\RevitAddInsManager.exe and double-click.

2. Identify Conflicting or Slow Add-Ins

   • In the UI, sort by “Last Loading Time” to spot extensions that delay startup.
   • Loading time includes DLL load and OnStartup execution. (Source: https://help.autodesk.com/view/RVT/2025.3/ENU/?guid=GUID-RevitAddInsManager)

3. Disable Problematic Add-Ins

   • Uncheck individual add-ons or entire groups (manifest files) directly in the Add-Ins Manager.
   • For stubborn add-ins that prevent Revit from launching, use the standalone application to disable them.

4. Apply Changes

   • Close Revit (if open) and restart. Changes take effect on next launch.
   • Settings are stored per Windows user. (Source: https://help.autodesk.com/view/RVT/2025.3/ENU/?guid=GUID-RevitAddInsManager)

5. (Optional) Organize Add-Ins for Easier Management

   • Group multiple commands in one manifest file; the file name appears as the group in the UI.
   • Add <Name>, <VendorId>, and <ProductDescription> tags in manifest files for clear naming and tooltips.
