Unty 5.xx ask yourself, Unity 4.6.7 can run on Windows 8 and Windows 7 SP1 32bit 32bit there?
But back when I installed it on an error like this
I cannot see the image, can you re-upload?
sory
Well, the reason is stated right there in the error.
Your installation is probably damaged or incomplete. Try to re-download the installer.
thanks
