IJ> I want to migrate from 64Bit to 32Bit... What's the best way??

If you are talking about going from 64-bit Windows to 32-bit Windows all you have to do is replace the .exe files.  All of the data is compatible between versions of Mystic, even between Linux and Windows and macOS and Raspberry Pi! 

You can even have Mystic automatically replace your .exe files.  If you download and extract the 32-bit version you can type:

install replace c:\mystic (or wherever your Mystic is installed)

It should find and replace all of your .exe files for you with the versions found in the installation you downloaded.

Now if you are using other things like Python, Cryptlib, or the spell checker then you will need to replace those installs/.DLL files with the 32-bit versions of each of those.
