To aid those deploying Altova Server Software products in the cloud, a free Azure virtual machine template is available in the Azure Marketplace. This template installs the complete line of Altova server software products, including DiffDog Server and the free LicenseServer, on the VM that you specify in the Azure cloud. Once you install the template, activate the desired products using the installed Altova LicenseServer to either request free, 30-day trial(s) or upload purchased licenses.
Free Trial Evaluation Information
To start your free, 30-day trial, simply download and install the server software you wish to evaluate, along with the free Altova LicenseServer.
Provided free-of-charge, the LicenseServer will allow you to request and manage free trial keycode(s). Upon request you will receive an email with your personalized evaluation keycode, which will unlock the software for 30 days.
All you need to do is install one instance of the Altova LicenseServer on your network and access it from any browser to request new evaluation licenses, enter purchased licenses, and assign them from one central web-based management console to any of the servers on your network.
