v3.9.1. “After online activation, DxO PureRAW 3 can be used offline for 37 days before a connection to DxO’s servers is required. Notifications advising that a connection is needed will be displayed after 30 days”
I’m not sure how to feel about this or what the policy was. I just never like “updates” which are essentially a forced acceptance of new terms for something I’ve already paid for. I travel a lot, but usually for a month or less. But who wants to worry?
To the extent of my knowledge, no DXO product(except for trials) has ever required an Internet connection except for activation at least back to Optics Pro 8.
I don’t remember the version numbers, but I used DxO when they ran a licensing engine with components that ran in the background. It was some OTS engine and I was happy when it met its demise.
