When I try to run SQLdeveloper, appears window with text "Please specify the path to the Java JDK home (eg C:\\Program Files\\Java\\jdk):". I enter my path, window appear again. I enter my path again, and that's all. Nothing happens. What I should do for SQLDeveloper start?

1. JAVA_HOME set to H:\\programs\\Java\\jdk1.8.0_11 .
2. File sqldeveloper.conf has text "SetJavaHome..."
3. C:\\Users\\username\\AppData\\Roaming\\sqldeveloper\\1.0.0.0.0\\product.conf has text "SetJavaHome..." too.

I think supported library files of sqldeveloper in your system are deleted,affected by virus or corrupted. So download fresh copy of sqldeveloper and try again.
