Ventana software support forum

Hi
I'm wondering why my Vensism software does not have sensitivity analyze option(No sensitivity icons, no toolbar)!?
I even re-install the software, but I'm still having problems
I use Vensim 6.4.
Thanks.

Vensim does have sensitivity, see

PLE doesn't, because it's targeted narrowly at learning about dynamics. PLE+ does.
