I'm also fond of the Portable Edition and hope newer Perl Versions will be supported soon.
But still, I can see the remains of an old installation can also sabotage the usage of a new Portable Strawberry.
One still needs to purge old remains, the advantage of a portable version is that there are none if it's the old version.
