1, c:windowstemp folder permissions are not enough, at least to give the USERS group readable and writable permission;

2, C:windowstemp folder full of disk, the file is not written in, empty the TEMP folder;

3, third party restrictions (such as the limitations of anti-virus software)

Workaround, start with the MY.CNF configuration first
