no_response.png Not receiving your Access Code?!


Might this be due to something wrong at YOUR end?!

If you do not receive a code within a couple of hours do not continue making repeated attempts within short time periods to obtain one. Doing so will automatically delay your request, as only your last request is digitally processed! Automatically cancelling all previously submitted requests.

Access Registration Codes are generated automatically and depend upon gathering information from the downloader's computer. Including geographic location (needed for providing local meteorological data); The computer's Operating System; The computer's keyboard type; What type of decimal point deliminator is in use (period or comma); Licensee entitlement (which programs are to be installed out of the more than two hundred programs Mistral produces).

It is therefore impossible for Mistral staff to generate Access Codes for licensees and to forward them. As Mistral staff do not have the necessary information to do so. The automated system ensures that Access Registration Codes codes can be returned 24/7, 365 days of the year, and in just minutes!


Mistral Associates are the developers of these fine Expert System software products. We have been doing this job for over thirty eight years and we know what we are doing by now. In addition to incredibly reliable, powerful and useful software products, one more thing you can rely upon from Mistral and that is a fast and always courteous response. If you didn't receive any reply at all, even after 24 hours, then the odds on chance is that the problem was at your end and not ours! If you have a problem and the solution was not found on Mistral's easy to navigate 3,200 page website, then contact us using our Feedback form. Explain clearly what you tried already, that is which pages you visited, immediately prior to submitting your request form.

When writing please be polite. Do not assume Mistral are in error. It is highly unlikely we are!
Aggressive or rude messages will be ignored and we will NOT reply to them!


Access Registration Codes for software are by their very nature codes.

Access Registration Codes don't read like normal text or words. Access for the software you are receiving is restricted. This is for protection of not just the developer's interests and rights but also those of the sponsors, also for those of our RAC industry and ultimately of course, yours!

This means that Spam interceptors may scan and sometimes block email messages that contain what they do not recognise as legitimate text. Particularly if they have been set inexpertly. So check with your email settings or your IT department or your Internet Service provider to see if email messages from Mistral Associates are being blocked by your own badly written or poorly managed Spam interceptor.


Have you allowed enough time for it to arrive?

The Expert System Software you are downloading and planning to install is a valuable resource. It didn't cost a few thousand Pounds to develop and constantly, on a DAILY basis, to maintain. It cost many millions! Access is therefore restricted to those that paid for access, and thus contributed to the costs, or, if that was not you, then someone else who is paying for access on your behalf.

The developer's normal office hours are 08:00 hrs to 18:00 hrs CET/CEST, Mondays to Saturdays and 08:00 hrs to 12:00 hrs CET/CEST on Sundays. The developer's offices are staffed 365 days a year. Mistral's offices do not close for national holidays. Mistral's staff do not stop for lunch. Please also bear in mind that international email routing issues can sometimes cause delays in transmission and which are entirely outside of the developer's control. Mistral's current local time is


Did you complete the request form accurately for example?

If your email address contained a mistake, or worse, you intentionally entered a false email address then naturally you won't receive a reply! (timewasters please note)


Has Mistral Associates' name been added to your Blocked Senders list?

Blocked either inadvertently by you or perhaps maliciously by someone else in your organisation. If it has then you will be unlikely to receive emails from us. It stands to reason. We won't even be able to communicate with you to advise you how to correct the problem!

Finally, you probably don't like to be ignored or even feeling rebuffed. To having your time wasted. Nor do we!
