Unable to auto Oracle after extension installed

I can not select any java element even if I have installed the extension and checked it. What other problem may cause this?

I have installed the Setup extension by using cmd launch(user is Administrator),and check all the files as the description in https://studio.uipath.com/docs/java-extension:
1)Using a text editor, such as Notepad++, open the accessibility.properties file, which is located in the C:\Program Files (x86)\Java\jre1.8.0_xx\lib folder. If the extension is properly installed, the file should contain assistive_technologies=UiPathV8.UiPathBridge.(ok)
2)In the C:\Program Files (x86)\Java\jre1.8.0_xx\lib\ext folder, you should find UiPathV8.jar and jaccess.jar (jaccess_1.4.jar for Java 4 or jaccess_1.3.jar for Java 3). If you use Java 3 or JInitiator 1.3, you should find the xml-apis.jar file in the lib\ext\ folder.
3)In the C:\Program Files (x86)\Java\jre1.8.0_xx\bin folder, you should find UiPathJavaBridgeV8.dll or UiPathJavaBridgeV8_x64.dll.123

My Uipath version is studio community 2018.1.4
My Windows version is win 7 32bit
My JRE version is 1.5.0_13
