Mistral installation error codes
Error #903 Not used (Error #903 should never be displayed!)
Error #904 seen when trying to install Mistral software means the code being attempted to be used is not a genuine Mistral Registration Code. Meaning it has been entered incorrectly.
Mistral's alpha-numeric access Registration codes have been made as easy as possible to enter. Firstly by eliminating letters in codes which can easily be confused. For example 'O' and '0' or 'I' and '1' or 'l'. Secondly by making codes non 'case sensitive'. In other words letters used in codes may be entered using either capitals or 'lower case' (small letters) with equal effect.
If having difficulty entering codes, and which can happen with exceptionally small computer monitors or for people with impaired vision, then try 'Copying & Pasting' the entire 24 character code, including the hyphens, directly into the code entry dialog box.
Error #905 seen when trying to install Mistral software means the code being attempted to be used is a genuine Mistral Registration Code. However if it is failing to install legally obtained Mistral programs then this will be due to one of three faults at the installer's end. Mistral's records show that reasons number 1) and 2) below are the most likely.
1) The Access Registration code is out of date.
Either because the code applies to a licence to use programs and interactive databases which are no longer current or because the code itself has passed its 'use by date', which is 30 days from the date that it was generated. Authorised licensees may apply to Mistral to issue them with a new code providing their licence is currently valid and this will be sent free of any charge. Access to programs and databases once installed will of course continue for the duration of the licenced period (either annual or 'lifetime'*) even when the code used to install them has passed its 'use by date'.
2) The Access Registration code is the wrong one for the program.
The Access Registration code that is being tried to be entered belongs to a different program issue. Either by date (a previous version for example) or to a completely different program or set of programs. (E.g. a code designed to install an individual program being applied to try and install Mistral's ‘Corporate’ program collection). Check to ensure you do not have more than one set of the Mistral program setup files (in a different folder) and that you are in fact trying to install the set intended. So as to avoid confusion unzipped program file sets from previous, now ‘time expired’ issues should be deleted from your computer.
3) The computer's system clock has been changed.
The target PC for installation has had its system clock reversed (either intentionally or accidentally set to an earlier date) at some time and then an attempt made to install Mistral’s intellectual property (software). This will introduce a blocking response in the affected computer and which can only be reset by an authorised Mistral engineer or manager (or a hard drive format). This is not just to protect Mistral against the consequences of intentional theft of its intellectual property (accessing software out of licenced time) but also to protect bona-fide licensees from accessing out of date code or no longer current data. The block will persist even if the system clock is subsequently reset correctly before an attempt is made to re-install (a ‘ratchet’ mechanism is employed which once set cannot be reversed without special measures). Mistral reserves the right to charge a fee for removing installation blocking codes. Particularly where there is evidence or a history of abuse.
* Programs installed using a 'Lifetime Licence' may not work correctly or may even cease to work altogether if the computer's Operating System is changed. This is because upgraded verions of Microsoft Windows frequently contain changes which affect program operation and which could not possibly have been anticipated by computer software developers at the time their programs were created. In this event it will be necessary to obtain the corresponding upgraded and compatible programs from Mistral. Program upgrades will NOT normally be offered free of charge! However, bona-fide lifetime licensees can expect to receive a substantial discount on the price of program upgrades. Mistral 'Corporate Licence' registered users all have their programs upgraded automatically as and when required, without incurring any additional charges.
Error #906 seen when trying to install Mistral software means the code being attempted to be used is for a different country or region of the world.
There are many diferent versions of Mistral programs which are designed to cope with regional variations. Such as those countries using commas as decimal point deliminators instead of full stops or countries normally using Imperial units of measurement instead of SI (System Internationale or metric).
Request a new Registration Code or in some cases also the re-issue of the software but set for the region you are in or if your computer is set for a different region to the one you are actually in than for the regional setting of that computer (not uncommon!).
If in doubt run Mistral's SETUP.exe program again but before proceeding please press 'Ctrl' + 'V' keys simultaneously. A form should appear which displays (amongst other things) 'System Locale:' and 'User Locale:' . Please advise us the code letters against each of these and we will revert as appropriate with the solution.
Error #907 seen when trying to install Mistral software means the user's computer system clock is incorrectly set.
Error #908 seen when trying to operate Mistral software means the user's computer system clock has been reset to an earlier date after the software was installed.
Error #909 seen when trying to install Mistral software means the code being attempted to be used is a genuine Mistral Registration Code but it is no longer valid. This means that you must obtain a new access registration code and which you may do so by clicking here. If you, or your organisation if relevant, are holding a current licence then Mistral will return a new updated access registration code for you. Generally within 24 hours and usually much sooner when during normal office hours (CET).
Error #910 Illegal activity with program code (details recorded on Mistral's server log but not made generally available).
Error #911 Users installing to computers that are part of a LAN (Local Area Network) must ensure they have full 'Read and Write' access attributes set for System Registry. A situation can arise where an installation appears to be successful, with access provided to all programs, but after shutting down the program the Access Registration Code input form reappears ahead of further attempts to restart. The Access Registration Code originally used to install cannot of course be used again. If this occurs then the user should consult their LAN Administrator to change the attributes for them ahead of attempting to re-install.
Error #912 seen when trying to install Mistral software means the computer's Operating System (Windows version for example) is no longer supported by the Operating System developer (Microsoft for example).
Error #913 seen when trying to operate Mistral software means the computer's Operating System (Windows version for example) has been upgraded after Mistral software was installed and where the upgraded Operating System may include features Mistral's software developers could not have anticipated and which has adversley effected program stability and/or operation. Consult Mistral Associates for details of a corresponding Mistral software upgrade. Mistral 'Corporate' and Subscriber Licensees will not be charged for this service.
Error #914 seen when trying to install Mistral software means the code being attempted to be used is a genuine 'single licence one time use only' code but which has already been used to install. Possibly by another authorised licensee. Holders of licences for multiple user installations should try completing the short, simple download and access registration code request form again and for EACH user that requires program access.
Error #915 seen when trying to install Mistral software means the code being attempted to be used has 'time expired'. Meaning too long a time period has elapsed between receiving the requested code and subsequently trying to apply it. That is more than 30 days has elapsed
Error #916, Error #917 Not currently used.
Error #918 seen when trying to download Mistral software means the downloader's IP address has been barred from accessing Mistral's intellectual property. Those affected will need to contact Mistral Associates to ask for an explanation of the reasons and (if appropriate) to appeal to have the bar lifted. Feedback. In the event the bar is not lifted following appeal then Mistral Associates reserves its right to not enter into any further correspondence on the matter.
Note: It is possible that an attempt to install fails due to more than one cause. However only one Error # code will be displayed. This being the most 'date sensitive'. For example a 'one time use only' code that is being attempted to use to install a second time would normally display an Error #914 code. However if that code was requested and generated more than 30 days before being applied again then Error #915 code will prevail and be displayed instead. If in doubt then consult Mistral via the Feedback form. Although in the first instance reading the simple to follow installation instructions might help!
