I tried to run my application and got this problem:
Could not load file or assembly 'Interop.ComUtilitiesLib'
After googling around, I found a way to fix that issue by changing the compiler option.
However, I really don't know how to change the setting of compiler options (in the project properties) to explicitly produce an "x86" (i.e., 32-bit) app.
What I see then view the project's properties were just: " Application, Build, Build Events, Debug, ... etc". Just the Compile Options disappears.
Select Build Menu -> Configuration Manager. On Active Solution Platform -> Select New or Edit.
