TC 6.5 with AES plugin 0.6.2 can decrypt files which encrypted with Winzip 9.0 new method - as it is in TC's history.
It was undocumented until now on part of plugin.
There is no special setting, just install the plugin as usual.
Note 2 Ghisler:
TC gives an error in addresses 00535C1F - 00000054 and crashes when you unzip a winzip-AES-archive when no AES plugin is installed at all OR when the plugin is installed under a different extension than .AES (I had .Crypt).
BTW: you also need to use the "zipcrypto.dll". With the default wcmzip32.dll you can't unpack these files because TC uses your default pkunzip.exe to unpack "password" archives first and does not load the AES plugin.
