Inferno not rendering on tyflow free (but formerly pro)

[Fabrice]

Hi,
I transfered my tyflow pro version from my old PC to my new PC.

On the old PC the tyflow scenes render well, but Inferno scenes wont render at all.
They appear in the viewport but when rendering it says:

"tyflow pro licence not activated.
tyflow volume rendering/API not found or activated."

And then the smoke and fire render invisible.

Do I need a pro version to render Inferno?
Is it because a previous pro version existed on this PC?

PS : I delete the old - formerly pro - tyflow_2027.dlo 
and replaced it by a new and freshly downloaded one. 
Without result.

(Win11pro + Max 2027 + tyflow free 2.100)

A PRO license needs to be activated in order to render, yes.

But you can render with a free licence right?
Why couldnt I?

No, you cannot render Inferno sims without a PRO license.

Ok ! I missed that specificity.
Thanks.

Why don't you just install version where your pro license is activated?
Licenses are permanent, and if you lost your license fairly recently, and if you could render inferno with your previous license, you can just go back to version where your license is pro, and render that out.

Yes but my goal was to network render other the 2 PCs, but with 1 pro licence that wont be possible for the Inferno scenes.
