You may try License Server in the cloud
If you want to try the License Server for callas' command line modules without installing and activating it in your network, you may use License Server in the cloud. This License Server runs in the public cloud at "trylicenseserver.callassoftware.com" and is easy to use with any callas command line module that has access to the internet. It must, however, not be used for production.
In order to retrieve a time limited session key for License Server in the cloud, please contact one of our partners (https://www.callassoftware.com/en/resellers-and-integrators-for-callas-software-products).
You will then get a session key that you may use with callas' command line modules using the --licenseserver and --lsmessage command line parameters:
./pdfToolbox --licenseserver=trylicenseserver.callassoftware.com --lsmessage=<session key> ./some.kfpx ./some.pdf
License Server in the cloud can currently not be used with desktop products, e.g. callas pdfToolbox Desktop.
