To install MySQL Server 5.0 in Windows Vista

1. Disable the UAC in Windows Control Panel->User Accounts (See the screen shot below)
   Windows Vista UAC turn off
2. Run the MySQL setup i.e. Use mysql-essential-5.0.51a-win32.msi
3. In the final step uncheck “Configure MySQL Server now”
4. Download and run Resource Hacker http://www.angusj.com/resourcehacker/
5. Open …\MySQL Server 5.0\bin\MySQLInstanceConfig.exe with Resource Hacker
6. Navigate to 24\1\1033
7. Change
   <requestedExecutionLevel level=”asAdministrator” uiAccess=”false”>
   to
   <requestedExecutionLevel level=”requireAdministrator” uiAccess=”false”>
8. Press “Compile script”
9. Exit Resource Hacker and save the result (overwrite the initial MySQLInstanceConfig.exe)

    a) Check Windows Firewall settings (3306/TCP)
    b) Try changing the compability mode for the file …\MySQL Server 5.0\bin\mysqld-nt.exe to Windows XP-SP2.
