Mistral Associates - News March 2020

Important update:-

Microsoft 'Code Signing'

code_signed.png Mistral has finally decided it has to progressively accede to Microsoft's bullying and arguably libellous tactics imposed upon the world's legitimate software developers. By applying Microsoft 'Code Signing' certification to all Mistral's already long time proven, world-class software systems. Software systems comprising more than one hundred individual program exe files. All of which are linked to tens of thousands of supporting code files, constantly maintained interactive databases and graphical image files etc.

Code Signing provides no guarantees of any kind for customers of any developer's computer program products. Code Signing does NOT involve checking of a software developer's products for safety, usability or even fitness for purpose. What Code Signing does do is remove Microsoft's arguably libellous statements displayed on screen when a developer's customer attempts to install their software, along with removing obstacles* to the user aimed at preventing that installation. What Code Signing does do by demanding that legitimate software developers pay regular 'Protection Payments' is create a substantial global revenue stream for Microsoft Corporation's world monopoly. Older software users may recall similar tactics in the England during the late 1950s and 1960s applied by a group known as the Kray Twins. Both of whom spent the rest of their natural lives in prison following conviction for their crimes.

* Unquestionably illegal under EC Consumer Protection legislation.


Microsoft Corporation are in a position to put Mistral's far smaller, albeit longer established organisation, out of business! At a time when the world faces a Global Warming crisis this would be especially regrettable. The amount of energy saved and consequential reduction in CO2 emissions that can be directly attributed to Mistral's world class, energy reduction related expert system software are incalculable! In any event the hard working team at Mistral are not prepared to simply write off the multi-million Euro investment made, and which it has continued to invest over a more than 30 year period in maintaining its renowned world-class expert system software. To say nothing of hundreds of thousands of hours highly skilled and demanding, hard work.

Mistral has therefore reluctantly agreed to start purchasing Microsoft's complex and tortuously difficult to apply 'Code Signing' code that removes the threats aimed at alarming our loyal customers and also frustrating software installation for our customers. Mistral's more than 30 year proven, world class products and which were originally launched before Microsoft Windows was even introduced! This code provides no tangible benefit or guarantees that we can see for end users of any software developer's product, including those of Mistral Associates.

Mistral regrets that due to this additional coding cost, coupled with increased, repetitive administration, this inevitably means we cannot avoid increasing the price of all Mistral program license access fees. As always Mistral will though endeavour to keep these fee prices to the minimum possible.
