Solidworks, launch crashes at "loading task panes"

Hello 

Thank you for your help, but I don't understand anything anymore, I'll leave you alone I'll see if I can manage otherwise 

Have a great day 

Kind regards 

Hello

To fix this kind of problem, pretend you want to install solidworks but instead of installing you choose to repair

You have to choose repair the installation, follow the steps and leave everything by default:
