There are two links to applications in this thread, it would be helpful if you could post some detail instead about which is not working or cannot be installed instead of making vague references, otherwise we have to guess/assume which is never a good thing to do...

OS 2006 software usually installs just fine on N800/OS2007 - to a large degree OS 2007 is backwards compatible with OS 2006 applications. If one of these applications doesn't install, perhaps you could provide some details about the error?
