J’ai récemment téléchargé Spat 5.0.9 pour Windows et suivi la procédure indiquée (voir fin de message). Cependant, aucune boîte de dialogue n’apparaît à l’ouverture de Max 7 pour activer Spat grâce à l’une des clés obtenues sur mon compte.
Par ailleurs, lorsque je lance spath.overview depuis le menu Extras de Max, les messages d’erreur suivants apparaissent :
Error -1073741795 loading external spat5.file.infos
Error -1073741795 loading external spat5.version

Merci de m’indiquer la marche à suivre !
A bientôt,

1) install the “Visual C++ Redistributable Packages for Visual Studio 2017″; you can (freely) download it from Microsoft website: https://www.visualstudio.com/downloads/.
Select “Microsoft Visual C++ 2017 Redistributable” and “x64″ and follow the instructions for installation.
2) unzip the spat 5 archive, and copy the content to your Max Packages folder
3) copy the following DLL files from the Spat package:
alongside the Max 64 bit executable i.e.: C:\Programmes\Cycling ’74\Max 7\
4) launch Max 64 bit

Il n’y a pas de boîte de dialogue à l’ouverture; c’est normal.
L’erreur -1073741795 en revanche n’est pas normale.
Quelle est votre version de Windows ?
Arrivez-vous à charger certains des externals de Spat ou est-ce que l’erreur affecte tous les objets ?

Merci pour votre réponse.
Je suis sous Windows 7 et il semble que le problème affecte tous les objets spat5.
Bien à vous,

Bonjour Basile,

Je n’ai pas Windows 7 sous la main, mais je crains que spat ne soit pas compatible avec cet OS.
Pouvez-vous essayer avec une version de Windows plus récente ?

Hi All,

I’ve just installed the Spat5 5.0.9 package from 10.1.19 in Max7 running on OSX 10.14.3. Max reports that it can’t load package spat5 “32-bit architecture unsupported”.

I’d be very grateful for any thoughts about why Max is reporting 5.0.9 as 32-bit. I thought it was 64.

Hi Tony,

Indeed, Spat5 is a 64-bit only package.
So, you have to make sure you run Max in 64-bit mode.
In the macOS Finder, select the Max application, and hit “command+i”. Make sure the “open in 32-bit mode” is unchecked.
Restart Max, click in “About Max” to make really sure it’s running in 64-bit.
(see attached screenshot)

Hi T.

Thanks for this, but 10.14.3 doesn’t have an “open in 32-bit mode”.

I also found this discussion:

but am unsure if the solutions suggested will fix the problem.

The Max7 I have installed is definitely a 64-bit version, see attached, but opens in 32-bit.

Would be grateful for any further thoughts or insights you might have on this issue.


PS I mistakenly took the error generated by Spat to be a Max error; it was of course Spat stating the Max was running in 32-bit mode.

The Max7 you have installed is both 32 & 64 bit.
Unfortunately it opens in 32 bit.
This is a Cycling/macOS issue, so you’d better post on their forum.

One “dirty” way to make it work is to type:
arch -x86_64 /Applications/Max7.app/Contents/MacOS/Max
in a Terminal. (you might have to adapt the exact path of the application)
This will definitely open in 64 bit mode.
However, I don’t know — in Mojave — how to change the default behavior. Probably some preference file somewhere, but couldn’t find it.

Other suggestions:
– using Max8
– trashing Max7 and all its preferences, and then re-install.

Good luck,

Hi T.

A further update on this: Max7 runs in 64-bit mode if run from the executable from within the Max7 package.

Thanks for the suggestion and help T. I’ll refer to c74.
