It took me a while to find out that I need SODE_VDGS_Pack_v.1.1 (bought several years ago at SimMarket, probably for v.1).
Really, this is something that should be mentioned IN CAPITALS in an installation section of the manual AND in a popup during install.
If that had been the case it would have saved me several hours.
Also... what's missing is a uninstall section in the manual.
