webPDF can basically be used on a 64bit Windows or Linux server.
A detailed list of the technical requirements and support for Windows or Linux versions can always be found in the current version of the documentation at "Technical requirements".
Under Windows webPDF is set up as a direct installation on the server. A corresponding link can be found on the page "Download".
Under Linux we provide packages for the respective package manager of the Linux distribution. You can find the corresponding information at https://packages.softvision.de.
