Hey Helder,
It looks like this error is caused by Windows; here's a Microsoft support article about it: http://support.microsoft.com/default.aspx?scid=kb;en-us;872903
It sounds like your user account may not have the necessary permissions. The article I linked contains more detailed instructions to try resolving the issue, but the first thing I'd try is installing LabVIEW as an administrator. To do this, simply right-click the LabVIEW installer and choose "Run as administrator". If the install still gives the error 1317, I'd try the steps in the Microsoft article.
I hope that works for you, but if you still need assistance after that, the information requested by the poster above would be helpful in resolving the issue.
