MCRinstaller compatibility with excel 32,64 bit

I am confused how to get excel add-in work. Please advice me.

I have written a code in Matlab2012b (64bit), on a windows7 64 bit. I created an excel add-in from my code, using visual studio professional 2010 (SP1) compiler.

>> mcrversion

ans =

     8

now if I want to use this excel add-in on different variations of windows xp/7 with 32/64 bit on excel 2003/2007/2010/2013 (excel can be 32 or 64 bit)... what versions of MCRinstaller should I install on the target machine? The excel add-in will be delivered as a part of a contract and should work on different machines of the target company.

I went through the guides in Matlab docs but I couldnt figur out what to do.

I just realized that the visual studio that is installed on my computer is 32 bit, so the matlab code is actually compiled with a 32 bit compiler. any comments on this?
