PTGui Pro 11.32 licence activation failure

[Béla Becker]

Hello!

We're having an issue activating our copy of PTGui 11

- When starting PTGui, the online activation fails with the error "Couldn't connect to the server", even though I'm able to connect to activation1.ptgui.com and activation2.ptgui.com in a browser

- The offline activation website tells me that the license is active on the computer that I'm on

This started happening a few days ago.

Hi Béla,

Windows might be preventing PTGui from contacting the activation server.
If you are in a corporate network, it's possible that network access has
been restricted, so you can access it in your browser but not in PTGui.

It's also possible that you may need to configure a proxy server to
access internet, this can be configured in PTGui Options / Advanced.

Regarding the offline activation problem: your computer's hardware may
have changed, causing PTGui to see this as a different computer. To fix
this, go to your account at https://ptgui.com/account , find your
computer in the list of activated machines and choose 'request
deactivation'. After the computer has been deactivated, try the offline
activatio again. Please contact sup...@ptgui.com if you need help
deactivating the computer.

Kind regards,

Joost Nieuwenhuijse

It turns out the issue was due to BitDefender enterprise antvirus
silently blocking the connection without any sort of a notification 🤬
Sorry for wasting your time, and also, thanks for the quick response!
