Adobe Reader DC - Is latest x86 msp file only works on X86 machines OR also on x64 machines?

Champs, 

I was trying to work upgrading msp file on both x86 and x64 machines. since I don't have older versions for adobe reader dc to test, want to check with experts if  latest x86 msp works only on x86 machine or also on x64.

X86 machine
x86 older version installed
x86 msp file -- upgraded

X64 machine
x86 older version installed
x86 msp file -- not worked
x64 msp file -- upgraded

x64 older version installed (not exist with me)
x86 msp file -- ??
x64 msp file -- ??

All Windows platforms include Intel 32, intel 64 and Arm 64. You do not need 64-bit apps just because you have a 64-bit system.

Adobe are slowly releasing 64-bit Acrobat Reader in certain parts of the world, but not yet for business deployment.

(Reminder: if deploying in a company you need a license to do this).

Than you, now it makes sense. I was unable to update the older exe with  x64 msp on x64 machie however it was working fine with x86 .
