As every user who has download access to Mathematica 9 for Windows from the Wolfram User Portal should know by now, a new version of Mathematica 9 has been made available for download.
This new version is virtually identical in terms of the resulting Mathematica installation. The major difference is in how the installer itself behaves while installing the application. The installer now attempts rather aggressively to resolve potential issues with font installation which may have created the preconditions for the blue screen system crash. All of the data we're getting back from users and from internal testing now indicates that this is fixing the problem.
As for side-by-side installations, it has always been and continues to be possible to install and run older versions of Mathematica along-side newer ones. The main caveats here are that the old one should actually work in your environment (e.g., some very old copies of Mathematica aren't compatible with modern operating systems), and that the number of concurrent processes you're allowed to run under your license is tracked across all versions of Mathematica.
