So i am trying to install this but it wont install , Keep getting this error . 
 

Sorry guys , After seeing it posted on here i think i have solved it , I changed the path of the 32Bit version to just Programme files/Cakewalk and left the 64Bit version go to Programmefiles/Calewalk/Vstplugins and it seems to be working . 

Usually the file for 32 bit versions is marked with an addition (x86).

Typically you would put 32bit plugs somewhere in the (32bit) Programme Files (x86) folder.

Yes, the 32bit and 64bit VSTs  for AD2 are both called "Addictive Drums 2.dll" so the MUST be installed to different locations.
 
Typically bapu? Hmm - not so sure as there are no hard and fast rules with VST2. This is better addressed in VST3.
I think we can agree that Mr. Bottomburp has not placed them in the 'best' location:
a. as they are within the Cakewalk stack
b. the 32bit VST in the 64bit Program Files tree
 
I wrote a VST strategy guide in the Steam Cakewalk Community pages some time back.
 
Assuming C\:Drive - Non-Steam Cakewalk VST2 locations are obviously replaced as:
32bit - C:\Program Files (x86)\Cakewalk\Vstplugins
64bit - C:\Program Files\Cakewalk\x64\Vstplugins
 
For Third Party VST2s, I suggest you should maintain your own and separate locations:
Say:
C:\VST_Plugins_32
C:\VST_Plugins_64
