Well I got that error too : when I used the last version marked as stable, but then I saw that the latest beta version had a bug fixed exactly related to this version.

So I used the beta version, and like I said, no error - but also no success.

Anyway - yes, I will have to use .7z type for my archives. Originally I thought I'd have to do backward compatibility for a product that already generates the archives, but eventually managed to isolate a specific part of the code I could change.

In short - I still thing that maybe there should be a message if the archive type is incompatible - but for my problem, I managed to just switch to 7z: and now I'm fine.

Thank you!
