RouteConverter and Mac OS X

[knuddelbacke]

Is that typical for an Mac application?

No. But here are some possibilities:

Typically you download a .dmg-file. After the download the .dmg-file is automatically mounted and opened. You will see the icon of an .app-file and an icon of a link to the application-folder. You just have to drag the .app-file to the application-folder and you're done.

Sometimes when the .dmg-file was mounted and opened you will find a .pkg-file (and sometimes one or more .rtf- or .pdf-files or something else). You have to double-click the .pkg file to start the install routine.

You'll also find just a .tar-file or the like you have to unpack and move the .app-file to the application-folder.

Seems the directory name is given as a file name to open. Do you know why?

Not really. After the download of your .zip-file I've found a folder called 'RouteConverterMac-1.33-SNAPSHOT' with an included file 'The RouteConverter UI tool for Mac OS X' in my dowload-folder. Maybe you should compress just the file not the folder with the file?
