This sounds like you're attempting to utilise the AS perlSVC tool against a different perl - if that's so, I wouldn't be at all surprised at the problems you're having.

As a complete hack, (I would'nt suggest this other than for interest) you could extend the script (that you're converting into a service) to add a new sub to the Win32 namespace...

sub Win32::BuildNumber {
.
.
}

I'm guessing that the sub returns the (what is laughingly called the) OS build level - a shortfall in your distribution perhaps ??
