How to install the network license ?


The LinkCAD network license consists of two components:

  • A shared folder on a shared server computer
  • A license fileĀ "lclic.net" containing the share path to the above folder.

When LinkCAD is being run, and it finds a network license file, it checks for the existence of the shared network folder. It then creates a runtime license in this folder, which will be removed when LinkCAD terminates.


  1. Create a shared network folder on your central server, e.g. "\\CENTRAL-SERVER\LINKCAD$". The dollar sign ($) is not required, but hides the folder from the Windows network browser.
  2. Give the shared folder the following permissions: Full Control (READ, WRITE, CREATE and DELETE) for all client computers.
  3. To verify the file permissions, please log onto a client computer, on which LinkCAD will be run, using a normal (not Administrator) user account. Create a file on the shared network folder, and then delete it.
  4. Send an email with the full share path (e.g. \\CENTRAL-SERVER\LINKCAD$) to [email protected].


  1. Once we receive your email, we will send you the network license file "lclic.net".
  2. If you haven't done so, download and install LinkCAD on all your client computers. You may download the latest version of LinkCAD from our web site.
  3. After you installed LinkCAD, copy the network license file to the LinkCAD program directory on each client computer (e.g. "C:\Program Files\LinkCAD 5").
  4. To verify the network license, start LinkCAD on a client computer. Then open the About... box (Help > About LinkCAD...). The licensed options should show the status "NET" (on a green background) next to them.
  5. You may also install LinkCAD on a single central server, and run the program over the network. In this case, make sure that the following files are present in the shared program directory: LinkCAD.exe and lclic.net. However, if the help file is to be found you need to install LinkCAD on each client computer separately.
