Adobe Reader DC 64 bit vs 32 bit Registry difference

Hi ,

Adobe Reader DC 64 bit ( HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall ) shows as  Adobe Acrobat DC in display name 

whereas in Adobe Reader DC 32 bit ( HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall )

shows as  Adobe Reader DC in display name  in registry 

Can i know why this difference ?

Thanks in advance 

Regards
