How to solve problem with DTMs which cause DTM catalog update failure or DTM failure

Description of the problem:
Some "old generation" DTM, cannot be executed in Unity Pro V11.1 (and later)
Symptoms may be :
•    update catalog fails
•    or DTM cannot be open

DTMs (non exhaustive list) :
•    Endress & Hauser Promag 100
•    Rosemount 8712E Magnetic Flowmeter Rev 3
•    Rosemount_644_Temperature_Transmitter_8_HART_000026_0018_8_DD1_4_181_4_DTM
•    Rosemount_2051_Pressure_Transmitter_10_HART_000026_2655_A_DD1_4_173_3_DTM
•    Rosemount_8712E_3_HART_000026_0057_3_DD1_4_173_2_DTM
•    Vega DTM

Root cause
Unity Pro V11.1(and later, Control Expert version included)  is compiled with Visual Studio 2012 and enables by default
Microsoftc Windows protection called DEP (stands for Data Execution Prevention).
DEP ensure a better protection against malicious codes attacks.
Previous versions of Unity Pro were compiled with Visual Studio 2008 that does not support DEP.

Here is a short explanation of DEP:
"The primary benefit of DEP is to help prevent code execution from data pages. Typically, code is not executed from the default heap and the stack. Hardware-enforced DEP detects code that is running from these locations and raises an exception when execution occurs. Software-enforced DEP can help prevent malicious code from taking advantage of exception handling mechanisms in Windows"

Some “old generation” DTMs generated years ago, are not compatible with DEP.
When Unity Pro or Control Expert loads it, Windows detects a risk in regards to DEP and throws an error.

Solution
Old generations DTM should be updated by manufacturer to comply with Microsoft DEP protection.

Alternative solution
DEP protection can be deactivated in Unity Pro or Control Expert.

Two solutions to do it, depending the Unity Pro/Control Expert version: Install the hotfix corresponding to your Unity Pro or Control Expert version.
Currently, the HF for Control Expert V15 is not yet available.
•    Close all Unity pro instances.
•    Download the Unity_DEPDeactivate.zip
•    Unzip the Unity_DEPDeactivate.zip
• Copy the files in the Unity Pro install directory, it is usually in : "C:\Program Files (x86)\Schneider Electric\Unity Pro"
•    Right click on file UnityDEPDeactivate.cmd
•    Execute as Administrator

•    Accept the security message
•    If okay, you should see
