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:
- Deinstall previous Unity
- Remove any remaining files in the installation directory of Unity
- Defrag your disk
- Verify your disk
- Check available free space (and deinstall any unused application)
- Reboot
- Wait for any ‘Repair’ actions (depending on what you did on point 4.)
- Reinstall Unity
You may eventually stop your antivirus/firewall during point 8.
