If you lost the License request, send us a email requesting the License code resend with your Order number, photo of the manufacturer plate or model and serial number of yous unit, screenshot showing Attach dialog with the unit in Mervis IDE or MAC address of the unit to [[:info@unipi.technology|info@unipi.technology]].
By using the Licence request you will get the following information:
* Mervis RunTime licence for unlimited functionality of the [[en:sw:01-mervis:02-mervis-rt|program running on the unit]]
* Mervis Proxy ID for use with [[en:sw:01-mervis:04-mervis-proxy|remote unit access]]

To get the licences, visit https://unipi.technology/getmervis and enter the **Licence request** code (it is necessary to sign in) and confirm by pressing the **Send request** button.
License request code **can be used only once** to obtain a license. If you use the request code for an account to which you later lose access, the license cannot be renewed and you must [[https://www.unipi.technology/mervis-p56|purchase a new license request]] to generate a new license. We therefore **recommend using request codes only on the main account** [[https://www.unipi.technology/getmervis|in the Unipi portal]].
The new licence will immediately appear in the list.
The first column contains the License request from which the other was generated. The next column "Mervis DB" is for the case that the generated license includes Mervis DB data. The Mervis Proxy column contains the **Proxy ID** for each PLC (license) and the **Mervis RunTime** column contains the licenses for Mervis RT. The last column "Note" is for the administrator note -> here we recommend to insert as much information as possible about which PLC uses this information and where it is located, or the project name.
