Requirements for "SharePoint Permission Analyzer"

Mar 15, 2016 at 4:56 PM
Where can I find the requirements to run the "SharePoint Permission Analyzer"?
When I put the Site link in the app and hit go, I get this error:
"3/15/2016 10:48:46 AM No valid site found at http://myURL.......................
3/15/2016 10:48:46 AM ERROR: Cannot contact site at the specified URL http://myURL... There is no Web named "My URL after .com/".
I am not running on the server but I have admin rights to this site. The site sits in another computer in the network.
When it asked username and password I entered my credentials for it.
Please help me use your app.

Thank you!

You need to be a site collection administrator.
