All new versions of Delphi can always be installed safely /next/ to older version.
Each new version should be installed in its own directory.
If you are going to install multiple versions, always install the oldest version first, and then work your way to the newest.
We work very hard to make sure that all versions of Delphi coexist together. But again, never install one version directly on top of another.
