I also have a Windows 10 machine and have just installed ABC Explorer 1.6.1 and it plays that file absolutely fine. I just copied the text from your post and imported it from the clipboard.

So it might be how it has installed. Permissions on your machine perhaps - it prompted me to run with User Account Control? You could try running the file as administrator (right click on the exe and run as administrator. I downloaded it from here.

I also pasted your text and saved as a test.abc file and again it worked fine
