Whenever I try to install the Titanium Appaccelerator it always fails to install JDK 6 (or newer).
When Titanium starts, a background process starts to download the JDK, when the downloaded package is opened an exception is shown: "Isntalling JDK has encountered a problem". No more information or details are provided by the dialog.
The JDK Path system variable may be missing.
Check the part "Updating the PATH Environment Variable (Optional)" from this manual: http://docs.oracle.com/javase/7/docs/webnotes/install/windows/jdk-installation-windows.html#path
