I am using Julia `v. 1.6.3` 64bit in my windows machine. I have an FMU model (generated by 32bits simulation tool) which I tried to load it. However, I got the below error.

```julia
ERROR: LoadError: AssertionError: Target platform is Windows, but can't find valid FMU binary at `` for path `path/to/file/myFMU`.

```

I am wondering if the problem is because:  
1- there are some other missing files that need to be existed? or  
2- this julia is 64bit and the FMU model is 32bit. If so, how can I let julia reads the 32bits FMU model? do I need to uninstall the current version and then install 32bit julia or there is a better way?  
This is what I get when from REPL of VS Code:
