Run a major upgrade installation to access the newest version of Automation Anywhere. It is not necessary to remove the old file; the process completely removes the old version, then guides you through installing and configuring the new version.

1. Run the Version 11.3 Control Room installer.
   An upgrade message appears.
2. Click Yes to continue.
3. Follow the steps in the Automation Anywhere setup wizard.
   Provide the configuration parameters on each screen of the installer and verify that the configuration parameters are the same as in the previous 11.x installation. If you are unsure about the exact configuration parameter values, see the aae-installsummary.html file in the 11.x installation folder.
   For more information, see Enterprise 11: Installing Control Room using Express mode or Enterprise 11: Installing Control Room using Custom mode.
4. Configure Control Room settings.
   For more information, see Enterprise 11: Configure Control Room authentication options.
   If you are using LDAP authentication on multiple nodes, see Postupgrade configuration of Active Directory for the steps to change the active directory configuration.
5. Click Finish.
6. Verify that the Control Room is properly installed using the Postupgrade checklist.
