Read the prerequisites and before you start before continuing.


To install ImageVault, follow the instructions below:

  • Download the latest version of ImageVault
  • Create an Azure Web app or an IIS web site.
  • Copy the contents of the installation zip to the webroot.
  • Assign modify access for the application pool user to the following paths:
    • /web.config
  • Navigate to the website and complete the setup.

Azure web app

To be able to run ImageVault in azure you need to create a web app that can run 64 bit applications. Today that implies a Basic web app at least. The web app needs to be configured accordingly.

  • .NET Framework version v4.6 (default)
  • Platform = 64-bit
  • Always On = true
  • Managed pipeline version = integrated

IIS web site

The site needs to be running on an application pool that uses the following settings

  • .NET CLR version = 4.0
  • Managed pipeline mode = integrated
  • Enable 32 bit applications = false

This is the default settings when installing on most 64 bit systems.

Always on

Always on is a function that will keep a web site always on. Normally it is only on when a client is requesting pages and will spin down if no requests are made to it. The always on function is used to maintain the scheduled jobs in ImageVault. If always on is not activated, ImageVault wouldn't be able to trigger the scheduled jobs in time.

Azure web app

In Azure web applications, the Always on is a feature that is configurable if you use an Azure Web app with SKU basic or more. You can activate it on the Application settings page.
