How do I sequence applications in MDT?

Problem

You need to control the order in which applications are installed during deployment—for example, installing dependencies (like .NET or Visual C++ runtimes) before dependent software (like Office or custom apps).

---

Solution

MDT allows you to control application installation order using one of two methods:

1. Application Bundles – group apps in a specific order
2. Multiple “Install Application” steps in a Task Sequence

---

Option 1: Use an Application Bundle

An Application Bundle is a single item that includes multiple apps in a defined order.

Step 1: Create the Bundle

• In Deployment Workbench > Applications
• Right-click > New Application
• Select Application Bundle > Click Next
• Name the bundle (e.g., Base Software Stack)
• On the “Included Applications” screen, add apps in the exact order you want them to install

Step 2: Use the Bundle in Your Task Sequence

• In your Task Sequence:
  • Find the Install Applications step
  • Select Install a single application
  • Choose the bundle you created

---

Option 2: Add Multiple Install Steps

You can manually add multiple “Install Application” steps in the Task Sequence for full control.

Step 1: Open the Task Sequence

• In Deployment Workbench > Task Sequences
• Right-click your sequence > Properties > Task Sequence tab

Step 2: Add Install Application Steps

• Under the State Restore phase:
  • Click Add > General > Install Application
  • Set each to install a single specific application
  • Repeat for each app, in the desired order

Example Order:

1. Install Visual C++ Redistributable
2. Install Microsoft Office
3. Install Chrome
4. Install Custom App

Best Practices

• Always install dependencies first (e.g., runtimes, .NET, frameworks).
• Avoid duplicate applications in both the bundle and separate steps.
• Use clear naming for application versions to avoid confusion.

Notes

• Logs for application installs are found at:
  • C:\MININT\SMSOSD\OSDLOGS
• You can apply conditions to specific install steps (e.g., WMI queries, roles).
• Application steps run in sequence; one failure may halt the deployment unless error handling is configured.
