Clifford is 100% correct! There is no "Emulation" mode required.
But, whether 32 or 64 Bit, you may find you need to install (and sometimes run) in "compatibility" mode. Right click the installation file (setup.exe: install.exe or whatever) and select from the tabs.
This is not a Bit issues, but, of course, 32Bit programs are likely to be older (XP or further back) and needing the compatibility option.
