Multiple Installations on a Single End User’s Computer

The Sentinel LDK Run-time Environment installer utilities contain an automatic mechanism that prevents more than one copy of the Run-time Environment from being installed on a single computer, even if multiple protected applications are installed on the computer.

The Run-time Environment installer utilities employ a counter that keeps track of the number of protected applications installed on a given computer.

For each installation after the first, the installer simply increments the counter instead of actually installing an additional copy of the Run-time Environment. Similarly, the counter is decremented each time the Run-time Environment is uninstalled.

The Run-time Environment is not actually uninstalled until the last protected application is uninstalled.
