You need to state the name of the principal user who originally purchased the software when ordering additional copies.
With a site licence you are licensed to make up to 50 copies of the software. The extension to the site licence allows you to make up to 250 copies within the site. If a person is employed at the site, they can take a copy home provided this is within the number of copies allocated to the site.
The principal user of a single user license is entitled to purchase additional copies at a reduced price. If there are only a few other staff who need copies, it may be best to buy additional copies through the principal user.
If there are a large number of staff requiring copies of MLwiN, it may be best to purchase a site licence to cover up to 50 users.

MLwiN compatibility with next generation Windows and Windows Server is untested
MLwiN has not been tested on any version of Windows Server, or 64-bit windows, Windows Vista or Longhorn, Windows Media Center Edition, and is not officially supported for these operating systems.
MLwiN has been designed for 32-bit windows environments. While we unofficially believe it will run in more advanced versions of Windows in the same manner as it does on the normal desktop systems, we believe there is not much advantage in doing so.
A possible benefit of running MLwiN on a 64-bit system would be that MLwiN might be able to get a larger chunk of the 4Gb 32-bit address space than usual. This would allow smoother processing and manipulation of very large datasets. However, we have not yet been able to test any 64-bit operating systems with MLwiN, and have been unable to confirm this. We plan to start testing soon.
MLwiN has been designed for a single CPU and is single-threaded. In multi-processor environments the most benefit MLwiN would gain would be that it could have one of the CPUs to itself without having to fight with other applications and the operating system.
Redesigning MLwiN to take advantage of multiple processors is a major undertaking, for which we have no immediate plans.
