When I try to start WSP, after login (user name and password is correct) I get download dialog instead of start of WSP.
It seem like security setting of OS (Windows 2012), but I was not able to find which one...
The server is not in domain, there is no GPO. It worked in the past, but now, I am not able to start it (WSP is not used so often, so I do not know how long is it in this state).
It is also profile independet (I try 2 different server users) and the same result is on primary and also secondary server.
Any idea what is wrong?
