Install Add-Ons

Add-ons are software programs that provide additional functionality for Autodesk software.

Some add-ons are provided to Autodesk subscribers. Other add-ons are available free of charge or can be purchased from a third-party vendor.

When you create a Revit deployment, you can include add-ons as part of the deployment so they are installed on target computers with the Revit software.

Note: Revit LT does not support the use of add-ons or deployments.

You can use command line options to control how an add-on is installed, which may be useful when scripting for automation. The options that are available depend on the method used to install the add-on.

To install an add-on from the Autodesk App Store

1. Exit Revit.
2. Go to the Revit page at the Autodesk App Store.
3. If needed, click Please Sign in First, and sign into your Autodesk account.

   Autodesk checks your status.

4. Select an add-on and click the blue Download button to download the installation file.
5. After the download completes, click or double-click the file to start the installation process.
6. Follow the prompts.

To install an add-on from your Autodesk Account page

1. Go to manage.autodesk.com.
2. If necessary, sign into your Autodesk account.
3. In the left pane, under Products and Services, click All Products and Services.
4. In the list of products, locate the desired Revit add-on, and click Download.
   Note: If the desired add-on is not listed, you may have already downloaded it, or your account does not have access to it. Contact Support for help.
5. After the download completes, click or double-click the file to start the installation process.
6. Follow the prompts.

When you start Revit, the Add-on tab displays between the Manage tab and the Modify tab.

If you encounter problems with the add-on installation, go to the Revit user forum for help.

Install an add-on with an MSI file

When an add-on has an MSI file for installation, it uses the Windows Installer (Msiexec.exe), the Microsoft® Windows® executable program that interprets packages and installs programs. The following add-ons have MSI files for installation.

• Advance Steel Extension for Revit
• Revit Extension for MEP Fabrication
• STL Exporter
• Structural Precast for Revit
• Roombook, Areabook and Buildingbook Extensions for Revit

For complete information about the Windows Installer, visit the Windows Development Center.

• For a list of command-line options, search for "command-line options".
• For a list of properties, search for "property reference".

Example 1: To install the add-on for all users on the target computer, use the property ALLUSERS=1.

msiexec /i aRevitAddIn.msi ALLUSERS=1

Example 2: To install the add-on for the current user on the target computer, use the property ALLUSERS="".

msiexec /i aRevitAddIn.msi ALLUSERS=""

Install an add-on with an EXE file

Some add-ons provided by Autodesk use the Autodesk install framework, which in turn uses the Windows Installer. The following add-ons use a Setup.exe file for installation.

• Revit DB Link

For these Autodesk-provided add-ons, you can use the options that are available when installing Revit from the command line. See Options and Parameters for the Revit Installation Command Line.

Example 1: The following command installs a product silently using the command line:

setup /t /q /c Prod1:INSTALLDIR="C:\Prod1\" Prod2:INSTALLDIR="C:\prod2\" setup.ini

Example 2: The following command uninstalls a product silently using the command line:

c:\Program Files\Autodesk\Prod2\Setup\Setup.exe /q /p {901C5280-ABCD-ABCD-ABCD-ABCDEF123ABD} /r Prod2 /language en-US
