RE4 Install Errors

I just got Resident Evil 4 brand new for the PC (via Amazon) and began installing it. At first everything was fine, then when it got about one quarter of the way done it had a error, so I hit "retry" and it then it worked. Then when it was about three quarters of the way done it had another error, so I hit "retry", but it didn't work. I then tried "retry" several more times before hitting "ignore" (it then worked again). I then experienced a third error, so I tried "retry" a few times, but it didn't work, so I had to do ignore (and yet again it continued installing). Eventually the install finished, however I have yet to see if it worked (I decided to make this post before actually trying the game). Below are screenshots of all three of the errors and my gaming rig ("gaming rig" is another term for "system specs" and "computer information").
