Besides User Group Picker PRO itself, there are also two dependencies, two complementary apps that are installed with it:

• katl-commonsSIL Engine™ – a library having countless utility routines, but most importantly, it contains a SIL language parser. You can think of the katl-commons as SIL engine for your SIL powered apps 
• warden – licensing support for several our apps
  
  

...

1. Download the User Group Picker PRO file from the Atlassian Marketplace.
2. Log into your Jira as Admin.
3. From Jira administration console, click the Manage add-ons link.
4. Click Upload add-on and select the file you downloaded, and click Upload.
5. If not already done, enable logging on our modules. Open with a text editor of your choice the Jira log4j configuration file JIRA_INSTALL_DIR/atlassian-jira/WEB-INF/classes/log4j.properties and add these 2 lines at the end of it. 

6. Restart Jira.

   log4j.logger.com.keplerrominfo=INFO, filelog log4j.additivity.com.keplerrominfo=false

What should I do if I installed an incompatible version?

...

1. Uninstall warden.
2. Uninstall katl-commons SIL Engine™.
3. Uninstall UGP Pro.

4. Install a version of UGP Pro that is compatible with your Jira version.
   katl-commons and SIL Engine™ and warden should now have the right versions as well.

5. Check any dependent apps, such as Power Scripts for Jira or Power Actions, etc. These apps must be re-enabled manually
