So I built a brand new system yesterday. Everything turns on and runs fine, no issues, but when I went to install Win7 on a fresh brand spankin harddrive I get the following message at about the 5% mark when Win7 is expanding files:
"Windows cannot install required files. Make sure all files required for installation are available, and restart the installation. Error code: 0x8007045D" (those are zeros) It's a brand spankin copy of Win7, product description is "Win Home Prem 7 SP1 64bit English 1PK DSP OEI DVD"

Any ideas what this means? Any assistance will be greatly appreciated.

Did you format the drive first? Also how is it set up in the BIOS, AHCI?

I also read it can be caused by bad media like the DVD or the drive being used to read the DVD. You said it's a store bought DVD and not one you burned yourself?

Is this an Upgrade or Full install version?? If it is the Full install you may have a corrupt disk. If it is a Upgrade version you need to install a previous version of Windows..

Thanks for the help so far!

It's Win7 full and newegg.com bought. It's the OEM version and on the disk itself it says "Intended for distribution with new PC." The choices for installing Win7 on the main screen are Upgrade or Custom. I chose Upgrade once but it wanted an older version, so I went Custom which says that is for systems that dont have previous versions of windows. I looked in the bios and didn't see anywhere to format the drive, I'll look again.

I should have said what the hardware is:

Keep the suggestions coming!

You should choose custom - even if there is data on hdd, you will be prompted to format the hdd
The bios can't format the hdd
Check the dvd for scratches or dust

Check the DVD if its clean, then its most likely RAM.

As in bad RAM or not in the right slots?

As in Bad Ram..

My Brother's system, I couldnt get windows7 to install, it would do everything, copy some files, reboot and then ask for the key, and lock up when the ram was set to the wrong speed. And when set tot eh right speed, it wouldnt copy certain files... rebotoed / blue screen w/ memory management or IO error.

I also had this problem on my system, when I used a copy that had been damaged some how (no scratches were visible, but parts of the disc wouldnt read.

try borrowing a copy from a friend.

if you have more than 1 ram stick, try running the DVD with only 1 stick present.

I suggest downloading and running Memtest 86 on each stick separately for at least 5 cycles each, then 7 cycles of them together in Dual Channel mode.

However I believe its either the DVD or the DVD Drive.

try downloading Western Digital's Program, and Format the Drive First.
Also Check SATA/IDE Modes in the BIOS, make sure there isnt anything that would cause the DVD Drive to corrupt

0x8007045D = Bad Media (its either corrupted from the DVD Drive, The Ram, or the HDD.


The Quickest and easiest thing to test is the RAM, So try Pulling 1 stick and running Windows 7 install.

I find mostly references to this being an I/O error, likely either the DVD Drive or DVD being bad and the installer unable to copy the files.
