This problem can be caused by a virus scanner and/or firewall. Try to turn off the firewall and virus scanner and check if it's working.
You could also try to make an exception:
- Create a folder C:\Temp\MySQLSvTemp
- Exclude this file form any virus scanner and Firewall activity
- Search for the my.ini file, this is normally located at: C:\
tmpdir=C:\Temp\MySQLSvTemp\
Save the file and reboot the PC
