I have Reinstall my unity already . but during installation there is error message and it can not be install! and to be like this picture [1153-06-06-2012+16-50-26.png|1153]

Potential issues: disk is full, disk has errors, lack of privileges (admin user?)

Try this:

  1. Deinstall previous Unity
  2. Remove any remaining files in the installation directory of Unity
  3. Defrag your disk
  4. Verify your disk
  5. Check available free space (and deinstall any unused application)
  6. Reboot
  7. Wait for any ‘Repair’ actions (depending on what you did on point 4.)
  8. Reinstall Unity

You may eventually stop your antivirus/firewall during point 8.
