The Clozure Common Lisp compiler does not install properly on Windows.

This is because the download is incorrectly packaged.

Once that is fixed I can package up a new gactar version.

Workaround

You should be able to download it and manually install it (I haven't been able to try it, but...):

• download the Windows release from here
• decompress it somewhere
• go to your gactar env folder and create a ccl folder in it
• copy the wx86cl64.exe and wx86cl64.image files into the env/ccl folder (make sure the files don't have ccl\ in the name)

Let me know if that works for you!
