Dear support,

Now we are trying to having a space for sharing file using Cyberduck with WebDAV protocol.
But we have some ploblems below.

1.We encounted the "Authorization error" with this situation.(but can with version 4.7)
--Cyberduck(version 4.8.4/4.9), OS(windows 7 Enterprise), Server(Windows Server2012 R2), Server softwear(IIS8.5)

2.If we can, don't popup the donation dialog or ads for our user. Is there the best way to not pop-up?Or can we buy something special volume licences?(no ads and no donate alert)

3.If we can't resolve the problem1, we also don't want the dialog about version up.

We'd serched in the existing tickets, maybe there are some related tickets of it(#9358, #9394).
Could you please help us and give a quick reply?(Sorry we have no time to concern.)
Thank you very much in advance.

Best Regards,
