I’m writing an add-in for an application which runs in 64 bit, however I need to use objects from a 32 bit library (this library only comes in 32 bit). Is there any way I can accomplish this?

This is quite easy in .NET. You just need all modules in a process to be the same bit-width.
So you simply start a child 32bit process, put all 32bit DLLs there, and use remoting features of .net to call procedures in it. Or as used to say in COM-times: Use out-of-process component server.
It will get more complicated when you need to pass a lot of data between 32bit and 64bit modules. You can setup memory-sharing, but it requires more work than normal.
