Windows installers, on linux?

Hi!

I need a (preferably) scriptable windows installer, and was wondering what my options were?

1) Wise - discontinuted and awful, not really scriptable
2) InstallShield - not really scriptable
3) NSIS
4) Others?

Also, I have a port of NSIS to linux, but I was wondering if there were any other installers which could build windows exe's from a linux box?

Of course, the more features and easier to use, the better ;)

Thanks for the help!
