Winamp won't play WavPack files

No, because that packages would install the runtimes you have already (Microsoft.VC90...)
However to install the mentioned 2005 Redistributables in Sandboxie (you would need admin rights) should give you the answer whether that are really the missing files, without changes to your "real" system.
If a sandboxed installation solves your problem I would install them in normal mode afterwards. Sorry for my English.
