Still no go here. Using the commands “JavaRa.exe /UPDATEDEFS /UNINSTALLALL /SILENT” with version 2.2 does nothing, except throw a .NET “unhandled exception” if the .DEF files already exists. Deleting the .DEF file allows another one to be downloaded, but then nothing happens. This occurs locally or from a network location. JavaRA.exe flashes in the Task manager but removes nothing. I have both 6u31 and 7u21 installed on the test machine. Basically, I want to uninstall all versions of Java so I can install the latest version. So far, I haven’t found anything that can do this.
