Installing and opening SDL Trados Studio on another computer

I have installed Trados Studio and Multiterm on another computer. When I try to open them a pop-up appears saying 'Do you want this app to make changes to your device? Below it says 'To continue, use an admin username and password'. There is only box which is strange. Also, which username and password are needed? The ones from my SDL account or the login details for the computer?

Thanks in advance.
