    3. Click on the Advanced tab.
    4. Click on the Settings button in the Performance section.
    5. Click on the Data Execution Prevention tab.

      To disable DEP:
        1. Click on Turn on DEP for essential Windows programs and services only.
        2. Click OK.
        3. Reboot the computer.
        4. Launch your Laplink program again.

Should the issue still persist afterwards, you can disable DEP globally (temporarily) as follows:

1. Press and hold the Windows key.

2. Press the letter R.

3. At the Run window, type cmd and press Ctrl + Shift + Enter on your keyboard.

4. The Command Prompt appears. Type the following to enable/disable DEP:

To always turn on DEP:  bcdedit.exe /set {current} nx AlwaysOn
To always turn off DEP: bcdedit.exe /set {current} nx AlwaysOff

5. Reboot the PC.

When later you are ready to roll back this change, use the command mentioned above in step 4 to turn DEP back on.
