Failed to obtain computer identifier

[atarkmeel]

Managed to install Solidworks somehow and can use it (as free period) but can't activate the license.
If Solidwoks starts it says - "Failed to obtain computer identifier. ..".
And on next screen can't cannot activate the license. It says "Unable to reach the license activation web site. .."
If anybody has an idea how to fix it. Maybe I missed some parts of the installation as script does not work fully for me.
Distro - latest Debian stable.
