You shouldn't use Archive::Tar::Win32 directly. Just use Archive::Tar, and it will use the Win32 version behind, to fix some resources that doesn't work in the OS Win32.

From the POD:
Although rich in features, it is known to not work on Win32 platforms. On those platforms, Archive::Tar will silently and transparently fall back to Archive::Tar::Win32.
