Ventana software support forum

Hi all!

I'm attempting to install Vensim PLE on Mac OS 10.9.1 I can mount the installer. But when I double click to install I get the following error:

["InstallVensimPLE" can't be opened because it is from an unidentified developer.]

I downloaded the install file using the latest version of Safari.

Has anyone else had this issue?

Any help would be much appreciated

Thanks!

You have encountered the OSX security system which injects a note of caution when opening executables which come from unregistered developers.

You should be able to open the file by right clicking on it and saying yes to any "are you sure?" questions.

Note, this mechanism cuts in for any files that have come from unknown sources not just Vensim.

HTH.

Brilliant thank you!

I will try that now
