Error when installing software

[68cobra]

I keep getting this error when i try to install software on my computer it says "the system cannot read from the specified drive". I used the disk in the drive and go the error. Then i made a copy as a iso to my computer then mounted it and it still says the same thing.

What happened before this started?
And what OS are you using?
