SQL : Probleme sur une requete MINUS

Bonjour, j'ai un petit probleme avec un minus..

Je sais que mes trois SELECT fonctionnent, le premier et le troisieme avec l'UNION fonctionnent mais quand je rajoute le SELECT du milieu avec mon minus...

Voila ce que me répond phpMyAdmin :
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'MINUS SELECT s.name, c.name FROM assetclass_isesoftware AS s, assetclass_isecom' at line 5

Si vous pouviez m'aider..

Merci d'avance!

voici ma requete:

SELECT s.name, c.name
FROM assetclass_isesoftware AS s, assetclass_isecomputer AS c, dico_soft AS d
WHERE c.ID = s.HARDWARE_ID

MINUS

SELECT s.name, c.name
FROM assetclass_isesoftware AS s, assetclass_isecomputer AS c, dico_soft AS d
WHERE s.name = d.EXTRACTED
AND c.ID = s.HARDWARE_ID

UNION

SELECT d.FORMATTED, c.name
FROM assetclass_isesoftware AS s, assetclass_isecomputer AS c, dico_soft AS d
WHERE s.name = d.EXTRACTED
AND c.ID = s.HARDWARE_ID
ORDER BY 2 , 1
