The vipb file is the build file I use in VIPM to generate the installable vip packages, and isn't intended for users. The vip packages I build can be found under releases (https://github.com/oysstu/LabVIEW-libsvm/releases).
I tested the library under win xp 32-bit in a virtual machine now with no issues. It's too bad that github features a big download zip button on the main page, when the most common way to distribute binaries is through releases.
