You don't say what error message, if any, you get when you try to install.
"Problem: When installing Insane an 'Error in data move process 117' is reported.
Solution: Select 'Typical Installation' instead of 'Full Installation'. If you have a Pioneer 114 DVD you need to update the drive's firmware.
If this does not cure the problem, it is likely that the disk is damaged."
