From the MySQL doc:
The preceding error is a typical message for Windows; the Unix message is similar.
One fix is to start mysqld with the --tmpdir option or to add the option to the [mysqld] section of your option file. For example, to specify a directory of C:\temp, use these lines:
[mysqld]
tmpdir=C:/temp
