Installation Note:Unlike standard portable apps which are installed to X:\PortableApps\AppNamePortable, jPortable is an add-on and is meant to be installed to X:\PortableApps\CommonFiles\Java. Once installed there, an application like Portable installed to X:\PortableApps\OpenOfficePortable will automatically make use of it.

jPortable 64-bit

jPortable is also available as a 64-bit variant for specific apps that support it to improve performance. Browsers and office suites will not make use of it. jPortable 64-bit will only appear in the Platform's app store with 'Advanced Apps' enabled.
