32bit to 64bit

You can run 32bit Setup from a 64bit desktop because a 32bit program can run on 64bits so a "down"grade will run.

But you cannot run 64bit Setup from a 32 bit desktop because a 64bit program cannot run on 32bits, so Bilal's reply is correct since the OP is going from 32bit to 64bit.

When, as in your case, you go from 64bits to 32bits you may find you have a Programs (x86) folder, which a 32bit version of Windows should absolutely not have. There are other anomolies. It is because the 32bit installer cannot remove certain 64bit elements
of the old OS.

It is not a good idea to "down"grade the architecture. It is safer to do a clean install of 32bits.

You may have a confused OS. I have done this (back when 64bit Windows first released) and I have no confidence in the results.

 

Upgrading 32bit Windows 10 to 64bit Windows10 on a tablet

Tablets often are locked to the 32bit version and cannot be upgraded to the 64bit version.

However, if it allows you this reinstall the OS, you do not need to enter any product key (incidentally product id is not an install code).

You have to be certain you install correct edition (3 versions - normal, single language SL or EU N version), or it will not activate.

Also, you should make a backup of current install (macrium reflect free is only tool I know that works reliably on 32bit eufi tablets).

Note : you can only clean install. You cannot upgrade from 32bit to 64bit and keep programs or data.
