Alex I can reproduce both methods. On two different computers.
 
1. X3e 64_Win 7sp1 64
 
2. X3e 64_Win 8.1 64

Alex, I can only reproduce the second (cannot drag a project file into X3 from windows explorer). With X3 open, double clicking a project file in windows explorer does open it for me.

Thanks. Are you sure you are running Sonar X3E as admin (via right click). If so I suspect your user permissions are set up differently. Ta

Yes, I have it default to that but also checked again for you. What I may have done with this was way back when someone had asked about the icons being "X1" so I have modified the HKEY_CLASSES_ROOT->Applications->SONARPDR.exe->shell->open->command to specifically point to X3 from this post.

If you have an administrator authority on your userid, why would you want to run as an administrator?
 
I ran SONAR as an admin, dragged open without issue and clicking in explorer opened without issue as well.

There you go, that confirms user permissions changes the behaviour (as it should).
 
I'm not really interested in the whys (people have different ways of doing different things for different reason), I'm just looking at reproducible bugs.

BTW if you run with my user permissions, you can run Wordpad as administrator, and then docs can be double clicked and dragged (and it will work). Sonar does not exhibit this correct behaviour (see steps #1), and has now been confirmed by multiple users (plus is reproducible by Cakewalk).
 
Anyway the issue is trivial.
 
Thanks...
 
p.s. I avoid administrator authority as much as possible when running apps as it keeps my system more secure. Same with user accounts.

An Administrator user account is NOT the same privileges for program execution as Run As Administrator.  Run As Administrator grants a higher execution privilege permission level than an Administrative user.

Quite true...
 
The user account that you create (or assign) as an administrator is not a true administrator account. It is a standard user account with administrator privileges. UAC triggers the true admin permissions for the user. If you are bonkers enough you could assign yourself to this true admin account (it's hidden somewhere I think), or turn off UAC.

Alex I just tried dragging and dropping and the project opened. X3E Producer.

Hi Alex, i did both methods. They are ok; they open as expected.
