Greg, thanks for answering !
Well, the thing is that I create my own WebApplication in Sharepoint throw API and create site etc... So I thing that installing is not a problem. But I`m fine when I do this:
Go to the "Solution Management" and undeploy solution with my form. Then I deploy it again and everything is cool ! So I`ll try to reinstall this and check it out again!
