To elaborate on my third bullet point "different versions": You could try out, either directly (using Strawberry's "portable" editions) or via
berrybrew:
- a 64bit Perl if your "normal" Perl is 32bit
- a 32bit Perl if your "normal" Perl is 64bit
- a Perl version that is older than your "normal" Perl
- the newest available one
Beware that all needed CPAN modules have to be installed on each Perl separately.
