For this to work you have to completely REMOVE one perl -- or install in another location -- this is the "safest" way

If you use the zip installer from http://downloads.activestate.com/ActivePerl/releases/ you can have multiple perls in different directories. Well, provided you edit Installer.bat before running it, so it doesn't pollute the registry 

## FORGET THESE
sub create_registry_entries
{   return warn "FORGET registry";
 
sub create_file_association
{   return warn "FORGET association";

sub create_script_mapping
{   return warn "FORGET IIS";


sub update_path
{   return warn "FORGET diddling path";

sub remove_html_shortcuts
{   return warn "FORGET html";

sub Set
{   return warn "FORGET REGISTRY ";

Also, you want to install 5.10.1 and NOT 5.10
