Re: associating .m files with matlab

DO NOT manually delete registry settings nor use fileassoc!
In R2010b, a new method for registering file associations was introduced. It allows multiple installed versions of MATLAB to have their own file associations (i.e. no more m-file progid). This allows you to easily switch your file associations from one version of MATLAB to another. To avoid the problem below, uninstall the pre-R2010b version of MATLAB before installing any of these newer versions. If you?ve already screwed things up, then reinstall the new version. These newer versions can be installed or uninstalled in any order.
