Running Complex Portable Applications in LiveXP

       I've created a portable version of Microsoft OUtlook 2003 which will not run under LiveXP. I've had difficulty with other portable programs including portable Firefox and Chrome.

       My question is--and I know this is overly broad--what are the differences between LiveXp and a full install of the operating system? Also is it possible to modify the build to make these porable programs work?

       My other thought was that if I can't run Portable OUtlook in LiveXP, what about running it in Portable VirtualBox under LiveXP? What adjustments would I need to make to get PortableVirtualBox to run?

       Basically what I'm trying to do is create OUtlook on a key that will run on any PC without depending on the native OS.

Thanks in advance for any suggestions.
