You should try below things
1: Verify your Java Runtime Environment (JRE) Version, make sure that it matches the requirements of Power Automate Desktop. Looking at images you given seems JRE 1.8 is installed, which is supported by Power Automate Desktop but check if the architecture (x86 or x64) matches the application's architecture.
Update your JAVA_HOME environment variable to point to the installed Java JDK directory.
2: Enable Java Access Bridge as Power Automate Desktop requires the Java Access Bridge for Java application automation. You can check it by opening Java Control Panel. Then Go to the Advanced tab.
Under Accessibility, ensure that Enable Java Access Bridge is checked. Restart your computer after enabling Java Access Bridge.
3: Run PAD.Java.Installer.Host.exe as administrator. Also confirm no errors are reported during installation.
You mentioned running PAD.Java.Installer.Host.exe. Ensure the following:
The required configuration file (pad.config) should be updated automatically.
4: Configure pad.config Manually (if necessary)
Locate the pad.config file (should be in the PAD installation folder).
Verify that it contains a reference to your Java application:
<java>
<jrePath>path_to_your_JRE</jrePath>
<javaAppPaths>
<javaAppPath>path_to_your_java_application.exe</javaAppPath>
</javaAppPaths>
</java>
Replace path_to_your_JRE and path_to_your_java_application.exe with the actual paths.
5: Check Java App Compatibility -Power Automate Desktop supports Swing and AWT-based Java applications. If the application is using JavaFX or other frameworks, PAD may not detect the UI elements.
6: Update Java Configuration - Ensure the JDK/JRE path used by the Java application matches the path enabled in the PAD Java Runtime Environment Settings. In the "Java Runtime Environment Settings" window, select the appropriate JDK/JRE and ensure it is enabled.
7: Recorder Settings - Open Power Automate Desktop. Go to Settings > Desktop Recorder > Java Mode.
Ensure Java Mode is enabled.
