If Expect doesn't install, this indeed won't work at all

The killer is that neither IO::Pty nor IO::Tty will work on MS Windows.

Do you use Strawberry or ActivePerl?

I generally use perls that I've built myself - using the 32-bit compiler from mingw.org or the 64-bit compiler from mingw64.sf.net. I do, however, have both StrawberryPerl and ActivePerl installed.

I don't bother too much any more with the Microsoft Compilers, preferring to use the mingw compilers instead - even with ActivePerl.

You may already be aware of this, but with ActivePerl and MinGW you can build anything that can be built on StrawberryPerl ... and more. (For mine, StrawberryPerl currently "is in front" simply on the basis of the non-core extensions that ship with it.)

Cheers,
