Opening .tblk file with root privileges Following the setup instructions for Tunnelblick I want to open the renamed .tblk file

After opening it nothing happens and no prompt in the tunnelblick app
I suspect this is because I am not opening it as administrator and it is a file downloaded from the internet.

How can I fix this?
Right click on the file, go under informations, scroll down to permissions and click on the lock. Then enter your administrator password to unlock it. Then, it you're not allowed to read, write and execute click on the +, select your username on the list and press select. Then change the combobox to read, write execute. 
Then, you should be able to open your file by right clicking and clicking on open with -> Tunnelblick.
