The only issues would be if the installer modifies global or shared 
aspects of the OS environment.

On Windows, for instance, only one version of LilyPond can be associated 
with .ly files at a time.  The most recently installed version would 
trump priors, unless you specifically disable file association during 
installation.  If you never double-click .ly files to compile them, then 
none of this matters.  If you do, then you would need to be careful when 
installing other versions to preserve the existing association.  And 
should the association get altered, you would need to manually 
re-associate with the desired version.
