Resolution: Make sure to install at the pre-requisites.

  1. Verify the pre-requisites here:
  2. Run our powershell script for setting up roles:
    1. Download the scripts link
      1. Just copy the content to a text editor and save it as InstallRolesAndFeatures.ps1
    2. Open a powershell prompt.
    3. Run the powershell script that was created in step 1.
      1. Hint one the file that was created, right click while holding shift. In the pop up menu there is an option to copy the file path. This is an easy way to get the fully qualified path to the file. Paste the value in powershell.
    4. The scripts are not digitally signed running them directly might generate a 'PSSecurityException'. If this is the case, use the following command to bypass the policy: powershell.exe -noprofile -executionpolicy bypass -file .\InstallRolesAndFeatures.ps1
  3. If this does not resolve the issue, follow the KB article on debugging the General Orchestrator Installation Troubleshooting .
