From Dave Burdick:
A couple of quick updates on the subject of 64-bit platform support for SkinVue.
For current SkinVue 6 PC users, you can download a multi-platform wxPython installer here in order to install either the 32-bit or 64-bit version of wxPython into your main Vue application folder:
This will allow you to run SkinVue6 on 64-bit PC platforms.
For the upcoming SkinVue7, 64-bit support is already built in to the product so there is no need to download the additional wxPython library.
