[AccessD] Access 2021 accde (64 bit) incompatible with Access 2013 64 bit

[John Colby]

can you do a decompile / compile under the Office 2021 32 bit compiler?
Send the resulting file to those clients still on 2013.  I think the
"Bitness" of the compiler is exactly the problem.  A 64 bit compiler is
going to make fundamental changes to pointer lengths etc.
You might have to run a virtual machine where you install a 32 bit version
of Office 2021 so you can do the compile under the 32 bit compiler.
