Error when updating module

Technical Support & Bugs

I got this error when trying to upgrade art (mostly with same-named files), and then attempting to launch the module from the Library screen with the Edit module command:

As requested, system specs.

Oh, and Java info…

This looks very much like VASSAL looking for the expected contents of the zipfile and not finding them. Can you post a screenshot of the root level of the zip archive? It should contain–at a bare minimum–a buildfile and one folder named “images”. It may also have a file called “moduledata” and perhaps .vsav files corresponding to predefined setups.

The very fastest way to do this with no file renaming required is to use 7zip, WinRAR, or any of several other utilities that will open a zip archive no matter what its file extension is.

Best guess, without looking at the module. is that you have an image filename containing a character that Java’s ZIP archive handling doesn’t support. (Is there an umlaut in one of your filenames, e.g.?)
