I’m pretty sure I know the answer, based on testing, but any previous post I found on the subject was a decade old.
Is there any reasonable way to have one end of the chain, the plugin in this case, be 32bit and have the application be 64bit?
Hi,
You can’t mix platforms so 64-bit host can’t consume 32-bit plugins.
from winapi - Load 32-bit DLL library in 64-bit application - Stack Overflow
You can only load a 32bit DLL into a 64 bit process when you are loading the dll as a datafile. You can’t execute the code. (http://support.microsoft.com/kb/282423)
It is worth pointing out that this is a hard operating system limit.
