@Pumauam could you open a terminal and launch jupyter notebook from there. Does it work, or do you see a traceback?

[Pumauam]

@goanpeca following your advice I opened a terminal and launched jupyter notebook from there. It didn't work (it just showed that it is not recognized as an internal or extrenal command, etc..)

[Pumauam]

By the way, spyder is working properly

[goanpeca]

@Pumauam did you open the anaconda-prompt, or just a "regular" windows command prompt?

[Pumauam]

@goanpeca I used first the regular windows command prompt. After reading your last message I found the anaconda-prompt. It neither launched jupyter but left the following traceback:

@Pumauam looks like some env var might be set incorrectly on your system. Take a look at https://github.com/jupyter/help/issues/5

[Pumauam]

@goanpeca, thanks, in the thread you shared with me the user sean13 wrote what it worked for him:

"Thanks! It was set to P:\User. I switched it to C:\temp and the notebook seemed to open! You guys are great!"

Apparently he switched from P:\User to C:\temp, however I don't know how to do that (change user) in the anaconda-prompt

[goanpeca]

@Pumauam what he meant is that that some environment variable was incorrectly set to wrong value (for some reason) https://kb.wisc.edu/cae/page.php?id=24500
