Maven M2_HOME set to an invalid directory (Windows 7)

Question

I\'ve tried installing Maven to Windows 7 with poor results. Some basic info:

Maven installation directory: C:\\Program Files\\Apache Software Foundation\\ap

Answer 1

Had an old version of MVN in another directory that showed up in the search path. Removed the old version and everything worked. Used windows file search to scan the drive for all instances of "mvn" to find the old version.
