Microsoft Power Automate for desktop can't access the elements of a Java desktop application.
Make sure that you aren't able to capture an element of the application by using either the Recorder or the "Add UI element" action in the Designer.
Cause 1: Java isn't installed on your machine
To solve this issue, make sure that you have Java installed. You can check this by:
Open a command window or terminal and enter:
> java –version.
If Java isn't installed on your machine, you'll receive an error message:
'java' is not recognized as an internal or external command, operable program or batch file.
Cause 2: Java Access Bridge is enabled
To solve this issue, make sure that you've disabled the Java Access Bridge in Control Panel.
Go to Control Panel > Ease of Access > Optimize visual display > Java Access Bridge from Oracle, Inc. Providing Assistive Technology access to Java applications, and then disable (uncheck) the Enable Java Access Bridge option.
Cause 3: Some files aren't available in the Java folder(s) of the machine after you install Power Automate for desktop
Specific files should exist in the Java folder(s) of the machine after the Power Automate for desktop installation.
Follow the below steps to check the installed Java version and installation path in your machine:
- Type Configure Java in the Search bar of Windows.
- Open Java control panel and go to the Java tab.
- Select View.
- Check values in the Path column. The row with Architecture equal to x86 refers to 32-bit Java installation, while the row with value x64 refers to 64-bit Java installation.
You may check the below files:
For 64-bit Java installation:
- File Microsoft.Flow.RPA.Desktop.UIAutomation.Java.Bridge.Native.dll should have been replaced in folder C:\Program Files\Java\jre1.8.0_271\bin. (jre1.8.0_271 could be replaced with your machine's Java installation.)
- File accessibility.properties should have been replaced in folder C:\Program Files\Java\jre1.8.0_271\lib. (jre1.8.0_271 could be replaced with your machine's Java installation.) If you edit the file with a notepad, it should have the following value:
- File access-bridge-64 should have been inserted in folder C:\Program Files\Java\jre1.8.0_271\lib\ext. (jre1.8.0_271 could be replaced with your machine's Java installation.)
For 32-bit Java installation:
Same actions for the same files as above but in folder path C:\Program Files (x86) \Java….
Make sure there isn't an .accessibility.properties file present in your user folder.
Check C:\Users\user if a file with name .accessibility.properties is present. If yes, rename it.
Ensure that VC_redist.x64.exe and/or VC_redist.x86.exe have been executed.
