That sounds like you are using the Personal Edition of QlikView instead of a licensed copy. Note that if you have a QlikView Server you can borrow licenses from the Server if it is properly configured, as well as using local site licenses. Make sure you have access to your QlikView Server and a valid assignment of license: open QlikView Desktop, go to the Start Page, select Open in Server..., set the server name or IP address and your user credentials, log in, and open any document.
That should lease you a license for 30 days.
Hope that helps.
Thanks for your time Miguel, but I still don't have an answer to my question, what I want to know is : even if I didn't create those files, let's say I have a qlikview server and then I copy all the qlikview documents you have in your computer and put them on my server, will people be able to see them even if I didn't create them, that's all I want to know.
