Ever since Vienna Assistant went to silent install I've been having issues with it. Running OSX 10.13.6. Sure it downloads each item as you click on it. If you then go to the page to install each download there's an activity indicator spinning in the Assistant gui and OSX puts up a windows asking for my system password to do the install and that's not the issue. The issue is the activity indicator just cycles and cycles and cycles and nothing gets installed. Or at least there's no indication that the install has been done. I end up having to force quit Vienna Assistant and manually install each update myself. Thankfully that works.
Also not a fan of the Vienna Assistant automatically updating itself. I've been bit too many times but something like this that installed an update my system couldn't use. Please go back to a system that allows one to update the Assistant if one wants to. And PLEASE fix the silent installer routine - it's broken.
Right now Vienna Assistant is only good for letting one know about updates and downloading them for those of us that aren't buying or authorizing anything.
