Any questions?
F.A.Q.
This section contains frequently asked questions by users of Artelys Knitro when purchasing, installing or using the software and our answers to these questions. For an answer to a specific question, please contact us.
Can I use all interfaces if I purchase the Artelys Knitro solver through a modeling language's website?
No. When Artelys Knitro is purchased through a modeling language vendor, Artelys Knitro can only be used through that particular modeling language or interface. To embed Artelys Knitro in a C/C++ or FORTRAN program, you must purchase the full Artelys Knitro libraries through Artelys.
Why does get_machine_ID.exe say the machine ID could not be determined?
On Windows this may happen if your machine is not connected to a network. The machine ID includes an Ethernet address, but Windows does not make the address available unless the network connection is enabled. See the Artelys License Manager User’s Manual for details.
