The solution of can ' t create/write to file error in MySQL

After testing the installed Supesite today, a MySQL query error is sometimes generated after modifying the user space template:

SupeSite info: MySQL Query Error
Script: /index.php

Error: Can't create/write to file 'C:\WINDOWS\TEMP\#sql_4f4_0.MYD' (Errcode: 17)
Errno.: 1
Similar error report has beed
dispatched to administrator before.

See this error first should consider the issue of permissions, if the C-disk permissions only open the Administrators group permissions, you can open C:\windows\TEMP give the directory everyone's permissions. Re-test if the problem persists, open the temp directory to see #sql _4f4_0.myd This file already exists, if the creation date is a few days before. Perhaps it is the last time you installed the access generated, you can empty the directory all, the problem can be resolved.

Attachment: This problem still appears today, on the server, it turns out that because McAfee antivirus software prevents the process from reading and writing to the file, McAfee has a feature that prevents programs from running and reading from the temp directory. It is resolved to add it to the exclusion range problem.
