Thanks for the post. Yes I admit the beta tag seems confusing but it is the latest and greatest version and you should certainly try to use it.
As far as installing, the new version requires a two part installation unlike the old version. The new requires a small 88mb download and then a much larger “pull down” of extensions. It’s the second part that can cause problems with company firewalls because it has to go out live to several “off grid” extension registries.
So you need to talk to your IT about temp allowing your workstation to get out to the internet uninhibited.
