No can do, you cannot downgrade Mac OS to a version of Mac OS earlier than what the Mac originally shipped with. You have choices though:
- Update the software in question to it's 64 bit equivalent.
- If you cannot do #1, replace the apps with other products that are 64 bit.
- Return the Mac and buy a used one.
