Turn off DEP for all programs except those essential to Windows


The cause of this issue is that on some machines (mostly 64bit or Server system) the DEP system feature is active.
DEP or “Data Execution Prevention” is a way of stopping certain software types on the machine from operating.
This feature is installed by default onto all Server machines and possibly 64bit desktop systems but not on the standard 32bit machines.
