I want to use a registry key to check if a prerequisite is installed or not. How can I do that in the "Install conditions" section to prevent the prerequisite from being installed?
Below I have attached an image of the registry. I want to find a registry value under the "Uninstall" key. Under the "Uninstall" key, there are subkeys by GUIDs. I want to find the correct subkey which has the desired "DisplayName" and extract some value from that GUID registry key.
