Thanks for the feedback!
Is it possible that you took the .exe out of the folder or something similar?
I wasn't, also I'm on W10. I think I found the issue, I think when I unzipped the rar, the unicode for the french dictionary filename got messed up, its "fran(garbage)is.txt on my PC currently. If you want to reupload a version that uses normal characters for the filename, I would gladly test again on my machine.
