And quite simple I might add

If you get: panic: top_env when running zone.exe with the embedded perl build, check your windows/system32 directory for perl58/perl56.dll or anything similar to it, delete it, and zone.exe will work again.

What's happening:
zone.exe requires perl.dll, which is quite often copied to your system32 directory. When it finds it in your system32 directory, it also looks for the perl libraries in the same place, which simply are not there.
