A RWS Trados Studio comprises of two main applications, RWS Trados Studio
itself and RWS MultiTerm Desktop and these are the two applications you need to
download from the Downloads area of your RWS Account and install.
There is also a 3rd application called RWS MultiTerm Widget that you will see in
the Downloads area of your RWS Account, but you do not need to install this as
it is for use in an Enterprise environment where you want to allow other people
in the organisation to access translations or terms relating to a document they
are working on. If this is of potential interest you can find out more about this
application here.
