The feature is disabled because of a security problem that any program
can be executed. In order to enable the feature, you have to change
the 'gsx:' part each time in the following way:

Option
Setup Parameters...
Graphic
   Check that Ghostscript is On(default)
   Add an option -dNOSAFER in gsx:
gsx:.../tlgs/bin/gswin64c.exe -dNOSAFER
click Save
click OK

Best,
