Without SoD, VT doesn't exist. VT is installed as a nested folder in the root directory of SoD. If desired, two SoD users can easily play SoD.
VT can be installed on WoG or TE. At the same time, you can specify any folder during installation. And, of course, it should be installed in a separate folder so that all versions work independently of each other.
A nested folder in the root directory with SoD is also essentially a separate folder, but why go to such lengths?
