Hi xz69Micky.
After upgrading to Cubase 6.5 (64-bit) I am only using vst-plugins supporting 64-bit. But I have just tried Virtual Guitarist 2 (Version 2.0.0.422) And it apparently works fine in Cubase 6.5 (64-bit).
VG1 does not show up in Cubase 6.5 (64-bit) - it is “blacklisted” by Cubase (see Vst2xBlacklist Cubase (x86_64).xml in the Cubase preference folder).
