I installed MySQL on Microsoft Windows 8 Using a noinstall Zip Archive. But when i tested by executing the following commands on windows prompt, the above error showed up.<
Though it is an old question, I am adding my answer in it, because the solution that worked for me on Windows 7 as an admin user, is missing in the answers' list. Though my solution is for installed MySQL, I am putting it for those who search for a solution for this error message. Here it is:
taskmgr
in the search bar Run as administrator
Services
tabMySQL
service and click Start Service
