Re: Fatal Error in Python.

Hey @DragonTiger321,


Thanks for being here! Have you tried to add Python to environment variables in Advanced Options?


I hope this helps, AndreaG

Re: Fatal Error in Python.

Yes, I've tried many times but still, this error is happening, and now there is no interpreter, it says it is missing.


Do I have to recover or backup my computer, I'm puzzled and can't find any solution.


Thanks for your help.

Re: Fatal Error in Python.

I googled it and found a possibly related, now resolved python bug.


If you can, upgrade your Python 3 to the absolute latest, or downgrade to a working 3.x. It is also possible your Python 2 may be interfering: you might try de-installing both, then install _one_ of 2.x or 3.x (but not both).

Please follow-up to let us know how you made out. For good karma, mark a reply as the answer if it helped!
