If the installer says you don't have enough free space (7Mb), but you're sure you do, hit "Go Back", then "Continue" and it should let you install properly. This affects the installer for version 1.2 on the CD dated December 2002.

If the Revolution Panel bounces in your Dock, then quits or does not launch at all, you can fix it by launching the Terminal in the Applications/Utilities folder and copy/pasting this text:

sudo chown -R `whois` ~/Library/Applications\ Support/

It will ask you for your admin password so it can fix the ownership of this directory. This is caused by a bug in our original installer. Hint: Always check our driver page for new installers.
