What kind of errors? You should have copy/pasted the
exception messages here.

Don't waste your time with that stupid "repair option". What
does an uninstall and reinstall process take these days...
all of two minutes?

Oh boy... The first rule of troubleshooting is always to
apply the simplist fix first, then start walking up the
"staircase of complexity" until you find a solution.
Something specific and esoteric as editing the registry is
very near the top of the staircase. In this case, the "easy
fix" is a quick and painless uninstall+reinstall. One of the
core philosophical principals of Python is: "In the face of
ambiguity, refuse the temptation to guess", and while
uninstall+reinstall may indeed seem like a drastic measure,
it is the most practical solution for this kind of problem.

(1) Uninstall all versions of Python on your machine.
    
(2) Install Python 3, and be sure to check the box that says
(I'm paraphrasing here): "Make this my default installation"

All better now?
