When I use anything that accesses a zipped file, like File… Zip Cookbook… or Unzip Cookbook…, I get “Error 449 Argument not optional”. What is happening?
This can occur if the version of the internal zip engine that NYC requires is not consistent with the installed version. The zip engine NYC uses is “activezip.ocx” – it is a shared file in your windows \system (or \system32) folder. If you use other applications that require “activezip.ocx”, either NYC or the other application may fail due to need for a different version of “activezip.ocx” to be installed as the shared file. Usually this problem can be fixed by downloading and installing the latest version of NYC, which will install the latest “activezip.ocx” file.
