Hi,
it appears that my company has updated the Network sniffing tool (we have Zscaler)...Whilst it was no problem on my old laptop 2 years ago the security has been updated and with the latest version this got blocked. Once my IT guy uninstalled it temporarily and disconnected from any VPN I was able to activate and it's running fine now.
No issue installing the Network sniffing tool afterwards - I guess Enpass just needs to be activated.
Thx
AJ
