Error message upon starting Blender

I’ve just downloaded Blender 2.28a…

…and recieved this error message upon starting it for thr first time,
(it happens every time I start it though)

‘Import site’ failed; use -v for traceback.

Now, I’ve looked in error message part of the Knowledge base, but it claims that this message only appears in 2.10 - 2.11.

IF I download the full Python package, will the error message cease?

One report I read states that the message does appear in 2.28, even with the full Python installed!

I know that Blender will run fine with this error message, but am I always going to get theses little niggles?

Any help

You need the full Python package AND a properly set PythonPath.
