I would suggest
re-reading the dialog text. I think it is asking you to compress or zip the WeatherCat
.app not a WC "folder". WC normally just installs the application, not a WeatherCat "
folder". You may not see the "
.app" part of the name because of Apple's somewhat silly default settings for Finder.
Most applications attempt to install themselves in the "Applications" directory. Therefore, you should find the "WeatherCat" there. Using Column view (although List view is almost as useful) in Finder may make it easier to find. First, make sure the "Sidebar" is showing (option-command-S) or look in the
Finder->View menu for "Hide/Show SideBar". Now select "Applications" in the Sidebar. "WeatherCat" could be at the top or the bottom of the Applications list depending on how you have it sorted.
If you still cannot find WC, use the Search box in any Finder window. Type in the full name: WeatherCat
.app otherwise you may find dozens of items). Somewhere in the Finder window (depending on the OS version) you should see a 'path' (a horizontal list of icons/names) telling you exactly where the WeatherCat application is. Or you can simply select the correct item in the Search results list.
Steps in getting ready to install WC 3:
- Quit WeatherCat (very important)
- Select the WC 2 application in a Finder window and use the File->Compress "WeatherCat" item. You will notice that this will not remove the WeatherCat.app, it will simply create a compressed copy of it. The icon will be different and you may see ".zip" added to the end of the compressed copy.
- Delete the WC 2 application and empty the Trash. (also important)
- Run the installer for WC 3.
- Restart WeatherCat
If none of this makes sense, that's my fault.
Just wait a few hours and a real expert will come by and offer better instructions!
