Is there a free trial for KRE (node-lock)? I downloaded the Katalon RE for mac(I could see only one option), but how do I know that if it is the node-lock or devops one? Also is there a free trial for these different types of RE? It is a bit confusing how to start using it. could you please point me to the right/latest document for activation. Thanks in advance!

Hi @jasmi There is no free version of KRE. There is a 30-day trial for KRE that require a business email (non-gmail, none-yahoo, none-outlook, etc). When you trial KRE, it is a floating license, which means you can use it on pretty much all environments. However, when the trial expires, you’d need to determine between node-locked license and DevOps license. Please refer to the FAQ of this page: [https://www.katalon.com/pricing/](https://www.katalon.com/pricing/) for more information regarding when to use node-locked and DevOps. ---

When you register a Katalon account, you’re automatically granted the 30-day trial. To use KRE, you need to download it from our page first. Then you need to create an AP key in TestOps (using the trial account) > **[How to use API Keys in Katalon Analytics](https://docs.katalon.com/katalon-analytics/docs/ka-api-key.html#create-an-api-key)** > > Instructions of how to generate and use API Key in KA Then you’d need to generate a command line in Katalon Studio using the Command Builder: > **[Command Syntax (Command-line/Console Mode Execution)](https://docs.katalon.com/katalon-studio/docs/console-mode-execution.html#command-builder)** > > Notes: Starting from version 7.0.0, you need a Runtime Engine (RE) license to activate and run Katalon Studio (KS) or Katalon Studio Enterprise (KSE) from the command line.

Hi @ThanhTo. We have now purchased 3 Katalon Enterprise licences for 3 test engineers. Now my question is again about the KRE licence. We have a Jenkins machine with Docker installed. We use Katalon Studio Docker image on that Jenkins machine. I assume that then we need to get Devops RE license for that? Now about installing them. We do have a company mail adress for installation of our test tools. Please let me know if the steps that I am describing below are correct for installing RE license 1. Create a Katalon account with the above mentioned mail account 2. Then we will get a Katalon studio package which has 30 days trial of both Katalon studio and floating KRE 3. Now I need to download the KRE on the Jenkins machine from your page 4. Then create a API key either as in [https://docs.katalon.com/katalon-analytics/docs/ka-api-key.html#create-an-api-key](https://docs.katalon.com/katalon-analytics/docs/ka-api-key.html#create-an-api-key) using the registered account or API key will be auto filled by the command builder. 5.Then generate a command line in Katalon Studio using command builder 5. Using the command the tests can be executed Please let me know if I am in the right direction for installation. Thank you! ---

Hi @jasmi Yes, that is the correct steps. Also, it is important to use (or extend from) our official Docker image. > **[katalon-studio/docker-images](https://github.com/katalon-studio/docker-images)** > > Docker images for Katalon Studio and other frameworks - katalon-studio/docker-images ---

Yes. We are using the official Katalon docker image. So After 30 days we need to purchase the Devops RE license, correct ? /Jasmi ---

Hi @roadbike Did you generate the command line which also contains the API key from the Command Builder in Katalon Studio ? Or you just generated the command line and then added the API key via copy-paste later ? There have been instances where people copy paste from a text editor and thus invalid invisible characters are also brought over. If the API key looks valid but in fact contains some invalid characters then it may explain why you’re not able to run it. Please check if this is the case. ---
