If you have 'renewed' your subscription floating licenses, here are instructions on how to create and install your new licenses.

You should complete this process on the day your previous floating licenses expire. As the 1 year starts from the activation date of these new licenses.


Stage 1: Generate and Download Floating Licenses

Login at then click on your username in the top right, and select ‘Activate Floating License’ from the drop-down menu.


You will be taken to the ‘Activate Floating License’ web page – this is the page where you will generate your new Floating licenses.


When you purchased a new subscription floating license, you were supplied with a new activation code. This activation code will let you redeem your new license files to use for another year from the date of the activation.

You have up to 30 days after the purchase date to activate your software, if you don’t, your 1-year subscription will start after the 30 days grace period.

Copy your new activation code either from the email you have received or from the ‘My Activation Codes’ page.


Paste the activation code on the ‘Activate Floating License’ web page, ensuring all of it has been pasted.

Copy the first MAC address of your RLM Server. You can copy it from the ‘System Info’ area on the RLM web page, which you can access by typing the address into your web browser whilst on your license server computer.


Paste the MAC address in the ‘MAC Address’ field on the ‘Activate Floating License’ web page


The host name and port can be changed in the future by editing the license file generated. This doesn’t invalidate the license file. However, it’s critical that the MAC address is correct as this cannot be edited, so always double check it after pasting it.

All that’s left is the Host Name of your RLM server.

Copy the Host Name from the ‘System Info’ area on the RLM web page.


Paste the host name of your RLM server in the ‘Host Name’ field on the ‘Activate Floating License’ page. Leave the server port as the default, i.e. 5053, unless your requirement is to use a different port, then click on ‘Generate License’


You have now generated your new subscription floating licenses for your RLM server. You can see the details for the licenses on the resulting web page.


You will now be sent an email with your new license files attached. Or another way to access your new floating licenses is to go to the ‘My Activation Codes’ page and click on ‘Download’.  If you do not see ‘Download’, instead you still see ‘Click to activate’, it’s likely that you haven’t refreshed the ‘My Activation Codes’ page after generating your licenses, so refresh it now.


Stage 2: Install Floating Licenses

Once you have your new floating license files (if your licenses are in a zip file, unzip them before proceeding), you need to install them by simply placing the new .lic files in the same directory as your RLM application on your license server computer – in this example it’s in C:\RLM License Server.


HDR Light Studio will disregard your old expired licenses once it finds your new active subscription floating licenses. If you want to you can delete your old and expired set of subscription floating licenses – but you don’t have to.

You now need to tell your RLM server software to restart and reread the installed floating licenses.

Open a web browser and go to the address if you’re not already there, then click on ‘Reread/Restart Servers’. Next, press the ‘REREAD/RESTART’ button. This will restart the RLM software and it will read the new floating licenses you have just installed.




Stage 3: Setup end user computers to use the Floating Licenses

Client computers do not need to be updated. Next time HDR Light Studio is run, it will pick up the new license from the RLM server.
