I ran into this issue with my desktop application 'Microsoft. I did not have the option to build as a 32 bit app. Hoping this would help others in the same situation. Installed the 64 bit version of Microsoft Access Database Engine Redistributable, as suggested by neo.
Although a more optimal solution is to simply recompile as suggested above, that requires access to the source code. In my case, I only had the finished. It uses CorFlags. Net SDK to change the loading characteristics of the application. You're done! This sets the starting flags for your program so that it starts in 32 bit WOW64 mode, and can therefore access microsoft.
