Windows 7: Windows 7 64-Bit Install Error - 0x80070241

Hi everyone. I've installed Windows 7 32-Bit RC1 on my desktop without issues using Daemon tools and mounting the ISO and installing to a separate partition, that's all very peachy. The original OS was Vista HP 32-bit.

Can't say the same for my laptop running Vista HP 64-Bit. Using the same method, the installer gets to about 12% and then comes with this error.


Windows cannot copy files required for installation. The files may be corrupt or missing. Make sure all files required for installation are available, and restart the installation. Error code: 0x80070241



I've downloaded more then 10 GB in the past 3 days re-downloading .ISO from both the Microsoft site and Bittorrent sites and seeing if they're corrupted. They're not. I get the same error every single time. Something else is the problem.

I tried installing BOTH the 32-bit and 64-bit inside my Laptop Vista 64 bit OS and I get the same error.

I've also unzipped the .ISO to my drive and tried installing that way. Same deal. Why did my Desktop go so smooth but my laptop is a living hell?

I'm really pulling my hair here. Any sugggestions welcomed.

At what speed did you burn the x64 DVD? Because of the extremely large size of the install.wmi file (over 2GB in size) a higher burn speed will most likely produce errors. I would suggest a re-burn at the slowest speed available.

Hope this helps

Hi Jeff,

I did not burn the files to a disk. I used Daemon as the emulator, and seeing that my 32-Bit install went smoothly with the mounter, I decided to do the same with the 64-Bit. But it obviously did not work. Guess I have to find a DVD lying around.

Dont think you can use 64bit install from a 32bit machine, i could be wrong?

No, I confused you XD, my Desktop had Vista 32-bit, installed Windows 7 32-bit.

My Laptop has Vista 64-bit, I tried to install Windows 7 64-bit, didn't work. Then I thought, "If the 32-bit installed fine on my desktop, Why not try it on my laptop?" It didn't work either.

***ISSUE FIXED***

Problem - While downloading the .ISO from Microsoft's site with IE and the download manager, the manager would hang at 99 % stating "Verifying Integrity" I stupidly ended the process, fearing that it had frozen up.

Solution - Re-Download the .ISO from Microsoft's site with IE, using the download manager. Let the Manager FINISH the ENTIRE process. It WILL hang at 99 % but it does not mean that it's frozen, leave your PC for awhile and the process will complete.

BTW - that's what I get for not having patience and letting the manager finish through.
