Data Execution Prevention - Is it applicable now?

It was advised with versions prior to LoadRunner 11.5 to disable DEP due to some limitations of Citrix protocol.

LR 11.50 does not mention this. But still if you want to proceed, select the option shown below. This is for Windows Server 2008.

Select System Properties->Advanced->Performance->Settings to get the below screen.

Select Turn on DEP for essential Windows programs and services only and click Apply.
