In fact there is 2 things:
1) In the install process :
There is a problem with this Windows Installer package. A program run as part od the setup did not finish as expected. Contact your support personnel or package vendor.
And it 'cancel' the installation
2) When I launch : http://<installed server name>:2431 or http://<installed server name>:9899
Message d'erreur de l'analyseur: Attribut 'targetFramework' non reconnu. Notez que les noms d'attributs respectent la casse.
Fichier source : C:\Program Files\Telerik\TeamPulse\UserManagement\web.config
So : targetFramework unknow. And it's in the file : TeamPule\UserManagement\Web.config
But, yes, you are right, I have almost everything install RC, RTM... So I will clean all this put the RTM everywhere, and wait for the last version which will come soon I'm sure ;).
Thank you for your reactivity, I let you know as soon as possible.
