The **Windows Custom App** Library Item lets you deploy Windows applications (MSI, EXE) to Windows devices. For details on installers, installation options, detection logic, commands, and troubleshooting, see the [Custom Apps Overview](/en/endpoint/library/library-items-profiles/custom-apps-overview#windows).

<Note>
  For what end users see when a **Windows Custom App** or **Auto App** install waits on running apps, including the system tray close-app prompt, see [User Experience with Windows Apps](/en/endpoint/library/library-items-profiles/user-experience-with-windows-apps).

## Create a Windows Custom App Library Item

To add this Library Item to your Iru Endpoint Library, follow the steps outlined in the [Library Overview](/en/endpoint/library/library-items-profiles/library-overview) article.

<Steps>
  <Step title="Navigate to Library">
    Navigate to the **Library** and select **Add Library Item**.
  </Step>

  <Step title="Select Windows Custom App">
    Use the **Search** field to find **Windows Custom App** by name, type, or label, then select it.
  </Step>

  <Step title="Assign to Blueprints">
    Assign the Library Item to one or more **Blueprints**. You can use Assignment Maps within Blueprints for conditional logic if needed.
  </Step>

  <Step title="Installation options">
    Choose **Install once per device** or **Install and continuously enforce**. See [Installation options](/en/endpoint/library/library-items-profiles/custom-apps-overview#installation-options-2) in the overview.
  </Step>

  <Step title="Enforcement timeframe">
    Set **Enforcement deadline** and, if you use **By enforcement deadline**, **Enforcement after version is saved** and **Enforcement deadline time**. See [Enforcement timeframe](/en/endpoint/library/library-items-profiles/custom-apps-overview#enforcement-timeframe) in the overview.
  </Step>

  <Step title="Enter application details">
    Enter **Publisher**, **Name**, and **Version**. Optionally add an **App icon** (.png). For more, see [Application details](/en/endpoint/library/library-items-profiles/custom-apps-overview#application-details) in the overview.
  </Step>

  <Step title="Upload app">
    Upload a .zip file containing the installer (MSI or EXE) and any supporting files (maximum 5 GB). Details are in [Installers](/en/endpoint/library/library-items-profiles/custom-apps-overview#installers-2).
  </Step>

  <Step title="Configure detection logic">
    Add at least one rule under **Detection logic rules**. See [Detection logic](/en/endpoint/library/library-items-profiles/custom-apps-overview#detection-logic) in the overview.
  </Step>

  <Step title="Executables for open app detection">
    Optional. Add executable names as described in [Executables for open app detection](/en/endpoint/library/library-items-profiles/custom-apps-overview#executables-for-open-app-detection) in the overview.
  </Step>

  <Step title="Select architecture">
    In **Architecture**, choose **x64** or **arm64**. See [Architecture](/en/endpoint/library/library-items-profiles/custom-apps-overview#architecture) in the overview.
  </Step>

  <Step title="Install command line parameters">
    In **Install command line parameters**, enter the full silent install command line. You can reference files in the zip with relative paths or run a PowerShell script from inside the zip. See [Commands](/en/endpoint/library/library-items-profiles/custom-apps-overview#commands) in the overview. If a path contains spaces, wrap it in double quotes, for example `"my installer.exe"`.
  </Step>

  <Step title="Uninstall command line parameters">
    In **Uninstall command line parameters**, enter the full silent uninstall command line. See [Commands](/en/endpoint/library/library-items-profiles/custom-apps-overview#commands) in the overview. Use the same quoting rule as for the install command when paths contain spaces.
