Win2K and latest version of CAVS

The version CAVS_Setup_2.0.17.58_Beta installed and ran just fine on my Win2K box. Today I uninstalled it and tried to install the latest version. It won’t install. It initially told me that I needed a Ux Theme.dll file, which I downloaded and installed, then another error popped up when I tried to install it again. Is this new version not compatible with Win2K?
