I like to have that available to be able to facilitate faster subsequent installs instead of extracting every time.
 
I'm a 4 installer person. 
 
32 bit on the DAW
64 bit on the DAW
32 bit on the Lappy
64 bit on the Lappy
 
Extracting every time is a PITA.
 
And while I'm at it; why can't we install both 32 and 64 bit in one install? Many VST vendors do it.

Thanks Bob.
 
I remember saving the X2 installer but just could not recall it's location.

You could use 7-Zip to unpack the d/l files anywhere you wish.
