# Adding or updating a License
The process for adding or updating a license is quite simple:
{% hint style="warning" %}
Please note, if you want to add a license onto a Codemeter dongle, the serial number of it has to start at least with 3-344.... If the serial number of your Codemeter dongle is older, you won't be able to add our license on it.
{% endhint %}
## Create a license update request - Machine locked
To create a license update request file from the container you’d like the new license to be on and send it to us. If you don't see any LightAct containers, please download [this ](https://lightact.io/wp-content/uploads/2020/09/LightAct-CodeMeterContainer.zip)file, unzip it and drag & drop LightAct.WibuCmLIF file into *CodeMeter Control Center*. Then an empty LightAct container should appear which you can use to create the license update request file.
{% hint style="info" %}
**Please note, this step applies only if you are trying to add a machine-locked license.**
{% endhint %}
The file has a *.WibuCmRaC* file extension.
{% hint style="warning" %}
Please note, you need to create a license update request from the container you want our license to be on.
{% endhint %}
\
To complete this step, open **CodeMeter Control Center** and select the desired container. In our case that would be *LightAct*. With it selected, click on the **License Update** button.\\
Select **Create lisence request** and click **Next**. \\
Click **Commit** to create a *.WibuCmRaC* file and save it to your machine. You can then send it to us via email at **.\\
## Create a license update request - USB Dongle
To create a license update request file open **CodeMeter Control Center** and select the desired USB Dongle. In our case that would be *CMStick/B 3-7771719*. With it selected, click on the **License Update** button.
Select **Create lisence request** and click **Next**.
If you already have a LightAct license and just want to update it, select **Extend existing license**.\
If you don’t have one yet, choose **Add license of a new vendor** and click **next.**
Type in LightAct's Firm code: **6001083** and click next.
Click **Commit** to create a *.WibuCmRaC* file and save it to your machine. You can then send it to us via email at **.
## Adding our license to your container
Once we receive the license update request file we will be able to generate a **license update file**.
The file will have a *.WibuCmRaU* file extension.
Once you receive the license update file, import it into **CodeMeter Control Center.** This time, choose **Import license update** instead.
{% hint style="info" %}
If you get an **Error: Import Update failed. Error 0**, simply **drag\&drop** the license into CodeMeter Control center.
{% endhint %}
After successfully finishing this step, the license will be updated or created on your container.
{% hint style="warning" %}
Please don't forget to apply the license in LightAct. The procedure is described the next article.
