You need to build the runtime on the platform its to be used on.
Once you have the runtime files, with the same bind key, the usr file should load between platforms
so after making changes, you can simply copy the usr into the windows runtime folder.
I dont deploy to the mac, so im not 100% sure, but I do know the non bound files run cross platform.
One thing is for sure, you need to first compile the runtime files under windows.
Thank you for your reply, SW!
So I need install FileMaker on Windows first and then compile it?
Thank you. I will try.
It works. Thank you very much for your help, SW!
