ERROR: LoadError: AssertionError: Target platform is Windows, but can’t find valid FMU binary

[Amuri44]

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.

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:

Dear @Amuri44,

a 64-bit application is not capable of loading (and executing) a 32-bit binary. Because you are using a 64-Bit application, there are no executable files in a 32-bit FMU. So if you want to use a 32-bit FMU, you can try to install a 32-bit Julia and run it in compatibility mode on your 64-bit OS. See here: Stackoverflow.
And finally, I did not implement 32-bit support, but if someone is using it and Julia is availabel for 32-bit Windows I can do so (only 3 lines of code).

EDIT: 32-bit support added in version 0.3.11

Best regards,
Tobias

EDIT: I will add support for 32-bit FMUs, but because all our testing-FMUs are 64-bit, we will (for now) only automatically test for 64-bit operation systems. Independent of that, you need to use 32-bit Julia.

I added 32-bit support for FMI.jl 0.3.11 (coming in around an hour). But this is not tested, I think some of the dependencies might not be compatible with 32-bit applications.

Dear @ThummeTo ,
Thank you very much for your explanations and your update of FMI.jl.
I have downloaded julia 32-bit on my (64-bit OS) and downloaded the FMI.jl 0.3.11. It seems to work for me at this moment.

Good to hear! Let me know if there are issues!

[Amuri44]

Sure, I will keep you updated. Thanks for your work.
