Does anyone have the recipe to fix the annoying message: "Cannot find a J2SE installed at path: C:\Program Files\Java\jre6"? I get the same message, when trying to set up and run SQL Developer on a Windows 2008 server with SQL Developer 32 bit, Java 1.6 and Java 1.7 32 bit, and now trying with SQL Developer 64-bit with JDK 64 bit. Thank-you.
