Sigasi Studio’s license key management system is based on the well known FlexNet (a.k.a. FlexLM) license manager. Sigasi Studio supports both node-locked and floating license keys. The Sigasi Studio edition is controlled by the license key.
This section details the set-up of the license server when working with floating licenses.
The version of the FlexNet daemons must be equal or higher than the FlexLM version of Sigasi Studio. The required version can be found in Sigasi Studio: Window > Preferences > Sigasi > License Key and look for the
- Windows (Windows 7 or newer):
- Solaris (on SPARC) [Deprecated. The last supported Sigasi Studio version is 3.6]:
By default, Sigasi license files use ports
27001 on your license server.
If these ports are already in use on the server, you can change the port numbers in the license file.
The port of the Sigasi daemon is set on the
DAEMONline. For example:
DAEMON sigasi port=27001, forces the Sigasi daemon to use port 27001.
The port of the FlexNet daemon is set on the
SERVERline For example:
SERVER your_server_name1 BD41FCF5DE27 27000, forces FlexNet to use port 27000. This is the port clients need to use to check out a license.
You can change the port numbers and your_server_name1 without breaking the signature. If you have a firewall, remember to open these ports for access.
the easiest way to start the Sigasi FlexNet daemon is like this (on Linux)
echo "Starting the Sigasi floating license server"
$LOCATION/lmgrd -c $LOCATION/sigasi.lic -l $LOCATION/debug.log
- Download the Sigasi daemon (see above)
- Create a folder to hold the license manager software, in this example we will use
- Unpack the zip file into the license folder (
- Run the license configuration tool
- Save the license file supplied for Sigasi Studio to the license folder
- Using a text editor, edit the license file and replace
your_server_name1with the name of the machine you are using, for example, from:
SERVER your_server_name1 74e50bb0911eto:
SERVER Maple 74e50bb0911e.
Note: If you are not sure of the name of the machine you are using click on the System Settings tab of lmtools, where it is shown, see below:
- Click on the Config Services tab and fill in the following, use the browse button when available:
- Service Name: Sigasi License Manager
- Path to lmgrd.exe:
- Path to license file:
- Path to the debug log file:
Note: You will probably need to type the “Path to the debug log file”, in full as the file will not exist so you cannot browse to it.
- Ensure both the following check boxes are checked:
- Use Services
- Start Server at Power Up
- Now click the Save Service button, and click yes on the confirmation dialog.
- Switch to the Start/Stop/Reread tab and start the server.
The license server should now be configured correctly, and looks a bit like this one
If your license key does not work, the first things to check are:
- Which version of the Sigasi license daemon are you using?
Note: The Sigasi 2 daemon needs to be updated to run Sigasi 3. Otherwise you will see an
License is not valid (Internal Flexlm Error)error message in the Sigasi Studio preference page.
- Is the MAC address correct?
- Since Sigasi Studio 4.3, on Linux Sigasi Studio uses the
ipcommand to list MAC addresses instead of the now deprecated
ifconfigcommand. If you’re using a version of Sigasi Studio older than 4.3 on Linux, you might need to install additional packages to obtain the
- On Arch, Debian or Ubuntu Linux, the “net-tools” package is needed.
- On (Open)Suse the “net-tools-deprecated” package is needed.
- Has the license expired?
- Did you copy the license string exactly as it was sent to you?
- Did you accidentally try to use a License Token as a license key?
- A License Token is a 24 character string. You can use your license token to Activate Your License Key .
- A License Key (or license file) looks like this:
INCREMENT com.sigasi.hdt sigasi 2.0 18-nov-2012 uncounted \
Doe;type:trial" HOSTID=ANY ISSUER=Sigasi ISSUED=21-Oct-2012 \
START=21-Oct-2012 SIGN="0CCC 87EA 9BB6 256E 7D81 E49D B2A6 \
E53D 1CA5 41D4 63DF 8671 5695 EF82 0E30 1028 732D DED3 0999 \
FD11 8B97 42B0 7CF2 F51F 20A0 DA6E 7F54 9D64 FF29 49AB"
If your floating license server does not function properly, try the following steps:
Start the FlexLM daemon with the
-zoption to see what is going wrong
You can check that the FlexNet daemon is running as expected by following these steps:
- Download the daemon zip file on the client machine
lmutil[.exe] lmdiag -c "<port>@<server>" -n
- If the server is running correctly, you should see a description of the valid FlexNet features served by you license server.
Make sure the server name in the license key file is correct.
Make sure both the Sigasi and FlexNet daemon are the same version (i.e. from the same zip-file from the Sigasi download server). If you need to mix versions, the FlexNet daemon version should be equal to or higher than the Sigasi daemon version.
- make sure that the port for the Sigasi FlexLM license daemon is open
- you can force the port for the Sigasi license daemon by adding USE_SERVER and DAEMON sigasi port=
to your license key
On Linux you might have to install lsb to avoid
No such file or directoryerrors when starting lmgrd or other flexlm tools:
sudo apt-get install lsb-core
zypper in lsb
yum install lsb
yum install redhat-lsb.i686
If the installation of
lsb-corefails (e.g. on Debian Linux 10), try this workaround (as root):
cd /lib64 ln -s ld-linux-x86-64.so.2 ld-lsb-x86-64.so.3
lmgrdlicense manager needs to have write access to the
/usr/tmp/path. If your system doesn’t have a directory
/usr/tmp, you can make a link to
/tmp(as root) :
ln -s /tmp /usr/tmp
You can not have spaces in the daemon path.
Some users reported that specifying an arbitrary absolute path for the Sigasi daemon on Windows (e.g.
DAEMON sigasi C:\\sigasi.exe port=27021) does not work. It only works if the Sigasi daemon is in the
C:\Sigasifolder. Other users have reported that you are not allowed to have the directory name being the same as the daemon name. For example:
c:\flexlm\sigasi\sigasi.exeis invalid, but
Make sure the environment variable is correct:
Verify that your server meets the License Server System Requirements.
If you try to run the daemon on an unsupported version of Windows, you will typically see this error message:
CreateProcess error code: 0xc1 File= sigasi.exe.
You can easily check the status of your license via the License Key preference page : Preferences > Sigasi > License Key. At the bottom of this preference page you can see the type and expiration date of your license.
If you are accessing your license server through an SSH tunnel, try using
Sigasi Studio pre-emptively tries to check out certain license features. As a result, you might see warning message like this in your server log. These messages can be safely ignored.
9:14:47 (sigasi) UNSUPPORTED: "com.sigasi.hdt.custom" (PORT_AT_HOST_PLUS ) testuser@testmachine (License server system does not support this feature. (-18,327:10054 ""))

If the steps above do not help, feel free to send us an email and send us a screenshot of the license dialog with the error message.
Check the content of the Sigasi License preference page via : Window > Preferences and Sigasi > License Key
- Is a valid license key path configured (or are valid environment variables used)?
- Is the user trying to use a Sigasi Studio 3 license in Sigasi 2.x?
Invalid license key (inconsistent authentication code)
- Did you correct the server name to the actual server name in the (floating) license key file?
