CrossOver installation failed

Hi all,

I'm new to CrossOver and I've discovered it recently, therefore I hope someone can help me fix this issue I'm experiencing with it at the moment.

I'm trying to install the free trial version in order to decide whether to buy the full one or not. Unfortunately, when trying to install it I get the following error message:

"Failed to run Python script '/Applications/CrossOver.app/Contents/Resources/libcxsetup-v3.py'"

Needless to say, my MacBook Pro runs on the latest version of the Mojave OS. Any idea why I'm getting this error and how it can be fixed?

Thanks a lot in advance for your replies.

Version 2 of Python comes standard on the OS X release — but you are being asked for version 3.

Try this:

Cheers,

Hi,

What is the ouput in terminal when you run "python --version"?

Thanks,
Anna

Hi Anna,

It says "Python 2.7.10". Should I follow John's suggestion?

CrossOver is not requesting Python 3. It uses the Python 2.7 that comes preinstalled with macOS. The "v3" in the error message is just referring to the third version of a particular file in our code.

Please do the following to collect more information:

  • Launch /Applications/Utilities/Terminal.app
  • In the Terminal window, type the following command and press the Return key:
    /Applications/CrossOver.app/Contents/MacOS/CrossOver
  • CrossOver will launch behind Terminal. I expect it will still encounter the same error. Dismiss the error dialog. CrossOver will quit.
  • Additional diagnostic information should have been written to the Terminal window. Copy that info and paste it into your reply here.

Thanks and sorry for the nuisance.
