lol... generally people with eBiz accounts on Mitel don't ask questions like this, my guess is he is an end user looking for software.
kwahodi, first try your vendor, if you purchased the system through them they should provide the software AND system password to you at no or a minimal charge. If not, or you have another unusual situation, PM me, as the software is not available to the general public, but in the famous words of Obi Wan Kenobi, "There are alternatives to fighting".
