configuration stopped at starting the server. and i uninstall the server and the workbench and deleted all the content and downloaded a different version of the server and it led up to the same problem.

Hi Mahgoub! Thanks for reaching out. Please open the my.ini configuration file that should be found in the following folder: "C:\ProgramData\MySQL\MySQL Server <version>\my.ini" Then, open the file and at the end, add the phrase lower_case_table_names=1 (or, if it is already there but it equals a different value, set it up to equal 1). Finally, save the file and try installing MySQL again. Hope this helps. Best, Tsvetelin
