... for Vista x64 users and whoever else needs it.
Be my guest and grab it from http://www.markusegger.at/.
XWA uses 16-bit InstallShield technology - no chances under Vista x64 (there's no 16-bit subsystem any longer). Only way out was to "reverse engineer" the setup process using a Windows XP workstation and create a new, Standards-compliant, state-of-the-art MSI setup from scratch (using the free Microsoft WiX toolkit).
Tested under Vista Ultimate x64 and Windows XP Pro SP2 - so hopefully there shouldn't be any issues left. Let me know if it works for you.
