Here's the error message I'm getting. I'm on a US realm and ran the script. It seemed like it was also on a US realm.

please make sure to install it properly.

if you're on windows, you can use icebox to insure you install it correctly.

I'm on a mac. Using Safari to download.

Safari may give you the option to open or save the file. Im guessing safari might be configured to open the file. If given the option you need to "save as" this will save the .zip file. When you open the file in your browser, it "ruins" the file as safari doesn't know how to open the zip file correctly, causing issues when you install in your interface folder.

Let me know if choosing "save as" helps at all.

this might help:

Switched browsers and downloaded with chrome. Got it after. Thanks, both of you :)
