having troubles with unicode in zip.zipfolders UDF i come across DotNetZip - http://dotnetzip.codeplex.com/

it seems have unicode support, but i cannot get to com interface of this library:

first:

c:\windows\syswow64\regsvr32.exe Ionic.Zip.dll

(here a complain about DllRegisterServer)

next:

#AutoIt3Wrapper_Autoit3Dir=C:\Program Files (x86)\AutoIt3\autoit-v3.3.12.0
;#AutoIt3Wrapper_Autoit3Dir=C:\Program Files (x86)\AutoIt3\autoit-v3.3.13.20-beta

$zip = ObjCreate("Ionic.Zip.ZipFile")
MsgBox(64,@error, IsObj($zip))

still no go - @ error = -2147221005
