When trying to extract the following password protected ZIP archive (password: zemana), Opus complains that the password is incorrect, but WinRAR extracts it fine:
dl9.zemana.com/LeakTest/key_sim.zip
Opus 11.10.3 beta x64 on Win 8.1.1 x64
Confirmed on my setup as well. 7zip accepts the given password but opus says it's wrong
How was that archive created?
Don't know. I simply downloaded it and couldn't extract it with Opus.
Ok, just wondered so I could try a few more archives. Anyway, I've found the issue and it will be fixed in the next update. Thanks for the report!
