Hitsiriaks ,Thank you so much, you saved my life. It's really interesting, I had the same problem in two different computers, the last one is a yoga 7 series pro 2021, which supposed to be a 'best'.nAnyways, from your line I had to adjust the version number that is the last one student version in 2021 (you can verify your version going into pc/c:/program files/Ansys Inc/Ansys student. Probably, this will help for future versions. move %appdata%\\ansys\\v212 %appdata%\\ansys\\v212.back Thanks, Oswaldon
