CADpass client secure connection (will be referred to as CADpass client or CADpass in this document) is a utility provided by CMC Microsystems that creates a secure connection between client PC’s, workstations, and computer sessions, and the CMC managed infrastructure.

This quick start guide provides instructions for installing the latest Personal Automated Design System (PADS) CAD suite, on a Windows 10, 64-bit system, using CMC Microsystems’ CADpass client to access shared licenses on the License Management System (LMS).

Prerequisites for Installing PADS with CMC License Manager System (LMS)

You must meet the following criteria before installing PADS:

  • Register with CMC Microsystems here:
  • Faculty supervisors must also register through the CMC subscription page at
  • Complete all required agreements for Siemens’ software use, which may be obtained at
  • You must have administrator rights for the computer on which you are installing this software
  • You must have a unique login name (Linux or Windows) that does not contain a blank space. A username such as “charlie brown” contains a space, while usernames such as “charlie.brown” or “charlie_brown do not.  The following are examples of unacceptable login names because they are not unique: admin or administratorcmcmgrrootstcmgrsupersysadmuserownerstudentguesttemp, and system.

References and Resources to Get You Started

To install a copy of the Siemens InfoHub manuals for PADS Professional, download both the HelpServer executable and the docs-pads-pro file from the same location where you found the PADS Professional archive on the CMC website. Click on the HelpServer executable first to install it. Do not change its default port settings, and do not allow HelpServer to be accessible over a network.

When the HelpServer installation is done, click on the docs-pads-pro executable. It will proceed to add the InfoHub tutorials and manuals on your workstation. These documents can be searched and opened in a browser, as shown in Figure 11.
