Hi - I’m running MacOS High Sierra and am having problems trying to install VectorWorks. In ‘System Preferences’ under ‘General’ I have selected to allow apps to be downloaded from ‘App Store and identified developers’ but still no joy! Any advice much appreciated! Update - I have done this too, but still no luck - http://osxdaily.com/2016/09/27/allow-apps-from-anywhere-macos-gatekeeper/ Thanks, Emma Update - I have been told that the free student 2014 version may be the problem and I need a newer version of the software to be able to install it - will keep you posted! Final Update - Went to 'Request Licence' and downloaded 2018 version - all installed & working nicely! Have suggested they include OS requirements for future users to save time and aggro!
