Licensing
Types - Network License
How
it works
Windows Version of FlexLM only (FlexLM for UNIX is not
supported)
- CAD Design Software uses the well-established FlexLM license manager from
Macrovision. Network Licensing
allows a license to “float” among various workstations on a network. It is sometimes referred to as a floating license. The
software is designed to release a feature license as soon as the command which requires the feature is finished. For
example if you finish using a command, your co-worker can use it immediately, as long as you do not use another
command which requires the same feature license.
- Setting up a Network License involves configuring a License Server and one, or more, Application Clients. The License
Server is the computer that runs the Network Licensing software. It can be any Windows 9X/NT/2000/XP machine in a network.
It can be, but need not be, the network file server. The Application Client is the computer running the CAD Design Software
application. The License Server can also be an Application Client. The Application Client must be able to communicate
with the License Server via the TCP-IP protocol. The advantage is CAD Design Software may be installed on
multiple workstations on the local intranet. However, only the number
of licenses purchased may use the software at the same time.

Installing
Read the FULL installation guide 
Procedure Overview in Brief
- Download FlexLM tools that includes the CDS Vendor Daemon and extract on selected server to be the FlexLM host.
- Use lmtools.exe on the System
Settings tab to gather information about license sever
(Computer/Hostname and Ethernet Address also know as MAC) and send the information to CAD Design
Software's license department at the following e-mail address: authcodes@cad-design.com
- Receive a license via e-mail from CAD Design
Software and follow the instructions in the e-mail.
- Create, Configure, Start and confirm FlexLM services for CDS is running.
- Set Environment Variable on client workstations
(Variable Name: CDS_License_File | Variable Value: port@host) See
How
to Set the
Client Variable
- Install CAD Design Software for client workstations.
- Run CAD Design Software

Download
the CDS FlexLM tools and Daemon
Flex LM License Manager
Utilities - Tools required for using network version,
including the CDS Daemon. This may also be used as an upgrade from previous versions of FlexLM
that you have obtained from CDS. If you have FlexLM from another vendor, you can still use a newer
version of FlexLM software because it is forward compatible.
Or just
use the CDS.EXE vendor daemon included in the zip file. For more information about FlexLM, visit
Macrovision.com
For EPD Versions 7.2 - 7.5,
use this version of FlexLM v9.5

For EPD Version 7.6 ONLY use
the FlexLM v11

Installing
a Network Variable for clients
- 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.
- Verify that the license server Vendor
daemon status is UP running
Windows 2000 / XP:
- Navigate to Windows Start>Settings>Control Panel and double pick the System icon.
- 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:
- In the Variable Name edit box, type CDS_LICENSE_FILE
- In the Variable Value edit box, type the port@hostid information.
Note, CDS uses the default port of 27000.
- Pick OK.
- The variable is now set.
- Pick OK on the remaining dialog boxes.

Upgrading to Windows XP SP2 Causes
License Problems
Symptoms:
FLEXlm Error -96. Server node is down or not responding. You
cannot get a license after your license server has been upgraded to
Windows XP SP2 (service pack 2). Please note that your local machine
is considered your license server if you have a nodelocked license.
For a floating license, this problem occurs when you are on a client
machine, trying to access a floating license.
Cause:
This problem is caused by the Windows XP firewall software on the
license server. Prior to SP2, the firewall was turned off by
default.
But after installing SP2, the firewall is turned on by default. The
initial settings of the firewall are set to block the communication
between your local client machine and the FLEXlm license server.
This means you will not be able to get a license without configuring
the firewall.
Solution:
To solve this problem, follow these instructions on your license
server:
Select Start->Settings->Control Panel.
In the Control Panel window, select Security Center and then Windows
Firewall.
From Windows Firewall, select the Exceptions tab.
Under Exceptions, press the Add Program button and then browse to
lmgrd.exe in the \CDSFlexLM directory.
Then, press Add Program again and browse to cds.exe in the
\CDSFlexLM directory.

The Desired vendor daemon is down
First make sure that the CDS.EXE vendor daemon is running.
- Open lmtools.exe
- Pick the service to view (CAD
DESIGN SOFTWARE)
- Pick the Server Status tab
- Pick the Perform Status Enquiry
button
- Scroll down to the line Vendor
daemon status (on server)
If running: CDS: UP vX.X
- If the vendor is down, it will
read cannot connect to license server.
- Make sure no other FlexLM services
are using PORT 27000.
CAD Design Software issues network license files with the
default port of 27000.
- To check other services,
return to the Service/License File tab
- Pick a service
- Pick the Server Status tab
- Pick the Perform Status
Enquiry button.
- On the line License server
status: port@server showing the current port assigned.
- If it shows 27000@server,
this would be the conflict.
- You may change the port number in
your CDS.PWD license file to a new port.
- Open the CDS.PWD using notepad
(see above).
- On the server line
SERVER server name mac address 27000
- Change the port 27000 to another
port that is free (ex 27010) and save/close the license file.
- Open lmtools.exe
- Select the CAD DESIGN SOFTWARE
service
- Pick the Start/Stop/Reread tab
- Pick the Stop Server button
- Pick the Reread button
- Pick the Start Server
button
- Pick the Perform Status Enquiry
button
- On the line License server status:
27010@server showing the new port assigned.
- Scroll down to the line Vendor
daemon status (on server)
- Should now say
CDS: UP vX.X
- Update the Environment variable on
each client's computer to the new port number.

Network
CDS.PWD license information
- The CDS.PWD license file can be
found in the \CDSFlexLM directory on the Host computer or use
Windows>Search.
- You may view the CDS.PWD file
with any ASCII text editor (Recommend Notepad).
- You may change the PORT in the
license file and save the license.
- You may change the path to the DAEMON
but you must use our cds.exe vendor daemon that comes with
the Flex LM 9.5 zip package available from the link
above Flex LM License Manager Utilities v9.5
