4 Steps to follow:

Step 1. Download FlexLM Tools

  • Obtain the FlexLM software Pick here

  • After Download, copy the ZIP file to the selected Server that will be the FlexLM server.

  • Open the ZIP file and pick the Extract button. Select the root of the boot drive (C:\) and pick Extract.

  • The zip file will create a new directory named “CDSflexLM” on the root of the C:\ drive.

  • Browse to the CDSflexLM directory and inspect the contents:


Step 2. Gather Server Information

  • In the CDSflexLM directory, double pick lmtools.exe and the lmtools dialog box appears.

  • Pick the System Settings tab to view the Host’s identification information.
  • The following information is required when submitting to CAD Design Software:

  • Computer/Hostname - This will be the computer’s Network name needed for license creation from CDS.

  • Ethernet Address - FFFFFFFFFFFF - a 12 digit hexadecimal number. This is the NIC (Network Interface Card) serial number commonly known as the MAC address. This number is required for license creation from CDS.

  • Pick the Save HOSTID Info to a File button and the Save As dialog box appears.

  • In the File Name edit box, type “system.txt” and pick Save.

  • The text file will be saved into the \CDSFlexLM directory.

  • E-mail the system.txt information along with All Company Information to to receive the license file.

  • You can close the LMTools dialog box when done.

  • CAD Design Software will verify the information and create a license file.


Step 3. Reading In License File and Configure

Notice: When CDS sends a Networked-type license, it will always be sent with a default Port of 27000 on the SERVER line. You may edit this value in the PWD license to an open port to avoid any conflicts with other FlexLM services that may already be using port 27000, Suggest a unique port like 27030 or 270134, etc.

  • After receiving the NEW license file from CAD Design Software, place the license file in the C:\CDSFlexLM folder that was created and rename it to cds.pwd (if desired).

  • In the CDSflexLM directory, double pick the LMTools.exe file and the LMTOOLS dialog box appears:

  • Pick the Configure Using Services radio button and then pick the Configure Services tab:

  • In the Service Name box, type (start over-typing existing text that is present)
    • Suggest using the service name: CAD DESIGN SOFTWARE.

  • Paths to set: 

    • C:\CDSFlexLM\lmgrd.exe - License Manager

    • C:\CDSFlexLM\CDS.PWD - License File

    • C:\CDSFlexLM\CDSFlexLM.log - Log file

  • Using the Browse button, set the Paths for the lmgrd.exe, the license file (CDS.PWD) and the Log file to the \CDSFlexLM directory as shown above. When pointing to the CDS.PWD, list the Files of Type to All (*.*) to see it because it will look for a *.lic file extension.

  • Select the Use Services check box

  • Select the Start Server at Power Up check box

  • When the settings have been made, pick the Save Service button and then pick Yes to save the new service

  • Pick the Start/Stop/Reread tab:


  • Pick the Start Server button. 

  • The Server will indicate Server Starting

  • Pick the Server Status tab and then pick the Perform Status Enquiry button. Scroll down to the line Vendor daemon status (on server) If running: CDS: UP


Step 4. Set Client Variable

  1. Navigate to Windows Start>Settings>Control Panel and pick Advanced System Settings

  2. Pick the Advanced Tab, then pick the Environment Variables button. In the System variables area, pick the New button and the New System Variable dialog box appears:

  3. In the Variable Name edit box, type CDS_LICENSE_FILE. This is important that you use this variable. In the Variable Value edit box, type the port@hostid information and pick OK. The variable is now set. Pick OK on the remaining dialog boxes.

  4. See more info on Environment Variables here

  5. NOTE: If the license server is also a workstation that will be using CAD Design Software, the same Environment Variable must be set on it as well.

  • After receiving a link to download, double pick the EXE.

  • Software will be installed in a new directory.

  • This will NOT upgrade previous version installations.

  • Follow the prompts or refer to the Installation guide on our website for detailed install instructions.

  • Once the software installation has completed, you must have a new CDS.PWD license file.

  • Once you have a new license file, run the software from the Start menu in the CAD Design Software program group.

  • Any previous version will still be accessible by running from the Start menu.

  • You may point the new install of EPD using the Technology command to your existing Library files or copy them (See Library Files below).

  • Any previous versions can be uninstalled to free up hard drive space or can remain installed.

  • Customers using the network version will have to use the same procedure except the license will need to be re-read on the license server (See Licensing below).

Library Files

  • These files are in a default location of

    • \EPD\HYB\, \EPD\PCB\, \EPD\SCH\, \EPD\ASY\Data, \EPD\Fab\Data

  • We always recommend that when using EPD components, you save them as a different name and not overwrite existing EPD data files.

  • Typically, custom design library files would not be saved in any of these directories.

  • New folders or sub-folders would be created (either in EPD, on a network drive or other location of the computer).

  • Browse these directories if you are not sure and check the date stamps on the files.

\HYB The default folders that come with EPD’s installation are the following:





\PCB The default folders that come with EPD’s installation are the following:




\SCH  The default folders that come with EPD’s installation are the following:




The SCH.DAT and LIB.DB files should be copied from the \SCH directory.

\ASY The default folders that come with EPD’s installation are the following:


\FAB The default folders that come with EPD’s installation are the following:



Manually Path EPD (add startup supports paths)

The Issue: During the EPD installation process, the user will be prompted to select an AutoCAD profile to install EPD. During this step, the user would select either <<Vanilla>> or <<Unnamed Profile>>. Then our install EXE would create the new profile and add 2 new entries to the “Start Up Path” in AutoCAD (See To Fix steps and graphic below).

TO FIX: The user will need to set the startup paths manually to the \ACAD and \ACDA64 folders located in the “C:\CAD Design Software\EPD 8.2” install folder.


AutoCAD Platform (see BricsCAD below)


1.      Open EPD+AutoCAD using the desktop icon

2.      Run the Options commands to open the Options dialog (or from Tools pull-down menu, pick Options)

3.      In the Files tab, pick the Support File Search Path to expand.

4.      Pick the Add button and then pick the Browse button and select C:\CAD Design Software\EPD 8.2\ACAD

5.      Now pick the new path (to select) and then pick the Move Up button until path is at top of startup list (see graphic below).

6.      Now repeat and Add and Browse to C:\CAD Design Software\EPD 8.2\Acad64, and Move up so \ACAD64 is now the first path and \ACAD is second (see graphic below).

a.      Note: These folders contain our executables or ARX files that load the EPD environment for a 64 bit computer (32 bit does not need the \ACAD64).

7.      Pick Apply and OK buttons.

8.      Exit EPD/AutoCAD.

9.      Run the EPD 8.2 desktop icon again and should load.


BricsCAD Platform


1.       Open EPD+BricsCAD using the desktop icon

2.       Run the Settings commands to open the Settings dialog (or from Settings pull-down menu, pick Settings)

3.       In the Program Options tree, pick the plus + symbol in the Files tree.

4.       Pick the Support file search path edit box to highlight it and a button with 3 dots appears; pick the 3-dot button to open the Folder List dialog.


5.       In the Folder list dialog, pick the Add Folder button and a new entry will appear at bottom of list with a 3-dot button.

6.       Pick the 3-dot button to browse and select C:\CAD Design Software\EPD 8.2\ACAD


7.       Now pick the new path (to select) and then pick the Move Up button until path is at top of startup list (see graphic above).

8.       Now repeat and add a second path to C:\CAD Design Software\EPD 8.2\Acad64, and Move up so \ACAD64 is now the first path and \ACAD is second (see graphic above).

a.       Note: These folders contain our executables or ARX files that load the EPD environment for a 64 bit computer (32 bit does not need the \ACAD64).

9.       Pick OK in the Folder list dialog and then close the Settings dialog with the upper right X.

10.   Exit EPD/BricsCAD.

11.   Run the EPD 8.2 desktop icon again and should load.
