Install the Mobile Access web server add-on for IIS

Use the standalone Mobile Access Runtime software to install the Mobile Access web server add-on for IIS.

Note: You need to have administrator privileges in order to install any software.

Before you begin this task, you need to have already installed the full Edge HMI software on at least one computer, even if you only use it for project development, because doing so also unpacks the standalone Mobile Access Runtime software installer that you need for this task.

If you want to install the Mobile Access add-on with the Embedded HMI runtime software on a Windows Embedded device, you need to install Embedded HMI first on that device. For more information, see Install Embedded HMI on Windows Embedded.

The Mobile Access add-on requires .NET Framework 4.8 or later, and if it is not present, the Mobile Access Runtime software installer will try to install it for you.

You can manually install .NET Framework 4.8 in Windows Embedded, but it is not practical to do so; both it and IIS should be included in the device's system image by the device manufacturer. If they are not, consider using the Mobile Access web server add-on for CGI instead.

In order to install the Mobile Access add-on on the computer or device that hosts your project runtime server, IIS needs to be turned on and the ASP.NET features required for Mobile Access should be selected. The Mobile Access Runtime software installer will try to confirm that IIS is turned on, and if it is not, the installer will abort the installation. The installer cannot also confirm that the ASP.NET features are selected, however, so you should confirm that yourself before you begin this task. For more information, see Turn on IIS for thin client access.

You should also enable Secure Socket Layer (SSL) encryption in IIS, especially if you plan to access your project over a public network. For more information, see Enable SSL encryption in Microsoft IIS.

There are two ways to install the Mobile Access web server add-on for IIS. The first way is to select Mobile Access Runtime as an installable feature when you install the full AVEVA Edge HMI software. For more information, see Install the full software. If you already did that, however, you do not need to do anything more and you may skip the rest of this task.

The second way is to manually install the software after the fact using the standalone Mobile Access Runtime software installer that is included in the program folder. You need to do this if you did not select the installable feature, as described above, or if you want to install it with the Embedded HMI runtime software on a Windows Embedded Standard device.

To install the Mobile Access web server add-on for IIS:

1. On the computer or device where you want to install the software, make sure IIS is turned on, but if the default web site is started, use IIS Manager to stop it.

2. Locate the standalone Mobile Access Runtime software installer (MobileAccessSetup.exe) in the program folder.

   The Mobile Access Runtime software installer default location on your computer is:

   C:\Program Files (x86)\AVEVA\AVEVA Edge 2026\Redist\WebAddOn\IIS\MobileAccessSetup.exe

3. If you are installing the add-on with the Embedded HMI runtime software on a Windows Embedded device, copy the installer to that device.

   You can either carry the installer on removable media (for example, a USB flash drive) or use the Remote Management tool (in the project development environment) to send the file directly to the device. For more information about the latter, see Download your project to the target device.

4. Run the installer, and then follow its instructions (that is, proceed through the installation wizard).

   You might need to run the installer as an administrator, if your own user privileges are not sufficient — right-click the installer, and then on the shortcut menu, click Run as Administrator. You will be prompted for an administrator's user name and password.

5. When the installation is finished, use IIS Manager to start the default web site.

To confirm that the add-on was successfully installed, run your project and then try to log on to the Mobile Access web interface. (This assumes you have already enabled and configured Mobile Access in your project, of course.) For more information, see Log on to the Mobile Access web interface.

If the web interface fails to load — that is, if the Mobile Access Logon screen is not displayed at all — use IIS Manager to confirm that your web server has started and the Mobile Access application pool (StudioMobileAccessPool) has been configured to use .NET Framework 4.x.

Finally, you should repeat this task whenever you upgrade the full Edge HMI software, to ensure that you are using the latest version of Mobile Access.
