#82: New version should supersede old in path
-------------------------------+--------------------------------------------
 Reporter:  ray at the.ug         |       Owner:  refold
     Type:  enhancement        |      Status:  new   
 Priority:  minor              |   Milestone:        
Component:  Windows installer  |    Keywords:        
-------------------------------+--------------------------------------------
 The Windows installer currently adds directories to the end of the Path
 environment variable. If one is installing over a previous version of the
 Platform, this means the ghc binaries from the previous version will be
 found first unless the path is manually edited. It should either remove
 the previous version's directories (if this is feasible) or insert its
 directories earlier in the path so the new version supersedes the old one.
