MYSQL Fail To start after setting???

[pun119]

I just config or change something with "MYSQL Server Instance Confiulation Wizard" and when I reach "Execute" and click it I get Service Fail to start.

IJust change "dfault character set" only.

Or shouldn't use or setting with this wizard at all?

I try to insert MYSQL data with thai langauage and it get "????" instate.

Do I need To remove MYSQL and reinstall it?

Or any suggestion will be very good.

Last time I got something like this with MSSQL I have to reinstall the server because I don't know what to do.

You can find errors in MySQL log.
It is a file servername.err placed at MySQL folder.

C:\Program Files\SWsoft\Plesk\Databases\MySQL\bin\mysqld-nt.exe: Can't create/write to file 'C:\WINDOWS\TEMP\ib2' (Errcode: 17)
060104 11:03:11 InnoDB: Error: unable to create temporary file; errno: 17
060104 11:03:11 [ERROR] Can't init databases
060104 11:03:11 [ERROR] Aborting
