This error occurred when installing MYSQL from a ZIP file without using the installer on windows7 64bit.
I write it down because it might be useful to someone.
Error details and solution
Can't open and lock privilege tables: Table 'mysql.user' doesn't exist
In my environment, it seems that an error occurred due to wrong setting of path in my.ini file of basedir and datadir.
In the case of windows, it seems that you must write two backslashes when setting PATH.
# These are commonly set, remove the # and set as required. basedir = C:\\mysql-winx64\\mysql datadir = C:\\mysql-winx64\\mysql\\data
If the old information remains, it will not be reflected, so initialize the MYSQL settings with the following command.
Then try installing MYSQL again.
By the way, MySQL Workbench makes it easy to create and manage MYSQL schemas.
