[Qgis-user] Qgis-messager d'erreur

[Fridolin CHOULA]

Au moment de lancer QGIS, je reçois ce message.
''Impossible de démarrer le programme car il manque qwt5.dll
sur votre ordinateur. Essayez de réinstaller le programme pour corriger ce
problème.''
J'ai repris l'installation, mais sans succès. Que puis-je faire?

>So, if I export the shape and want to load it in another GIS, the associated
