64 bit accessing 32 bit application error


Mixing 32 bit with 64 bit it is not allowed – see https://support.microsoft.com/en-us/kb/282423 .

However, there are several solutions to accesing 32 bit from 64 bit :

1. Simpler – create a console exe (32 bit) application that calls the library ( same bit version) . Use this from the main program.

Cons: Error handling , difficulty to debug

2. Complicated :Read this and make your solution https://blog.mattmags.com/2007/06/30/accessing-32-bit-dlls-from-64-bit-code/

3.Use a NUGET package to call 32 bit from 64 bit.
