Hi, I am Nigel, Independent Advisor here to work with you on this issue.
Starting with Windows 10 Anniversary Update, you can setup a dual boot configuration with another instance of Windows 10. It is not permitted by the license agreement, but it still activates. Microsoft's recommendation for remaining in compliance is to purchase an additional license agreement. So if you are running Windows 10 64 bit now, and you need 32 bit Windows 10 for compatibility purposes, you can do so by installing it on another partition.
Virtual machines would be a better option however
A virtual machine is an option.
If you are a running Windows 10 Pro, consider Hyper-V: How to setup a virtual machine using Hyper-V
If you are running Windows 10 Home, look into the following: How to: install the latest Windows 10 in Oracle VirtualBox
