Note:

Lifetime Licence means exactly what it says. However, please be aware that if upgrades to a PC Operating System render a program installation inoperable, then Upgrades will only be supplied free of charge for 2 years following installation. All Mistral Expert System software is, quite uniquely, 'backwardly compatible, meaning results created by Mistral programs as far back as 30 years ago can still be opened, edited and re-saved if desired. However the opposite, that is 'forward compatibility' is of course technically impossible.

If the requirement to upgrade Mistral Expert System software is necessary in order to meet unexpected challenges presented by future Operating Systems (Microsoft Windows), although rare, is not unheard of. Mistral Lifetime Licensees will though be respected appropriately and upgrades supplied at the absolute minimum viable cost. This might reasonably be expected to be in the order of 50% discount or even more.
