Windows cannot copy files required for installation. The files may be corrupt or missing. Error code: 0x80070241.

Hi,

Method 1:

The error you encountered might be cause by a DVD image or a corrupted one while burning to the disk. Try the suggestion from the post below, reburn your copy of the installation CD/DVD with a lower speed and nothing else running on your system.

Method 2:

Step 1:

Run Windows Upgrade Advisor to see if there are any known issues that might affect the installation and fix them.

Make sure your computer has the most recent drivers.

Disconnect all external devices except keyboard and mouse before installing.

I'm not trying to be rude but you did not read my entire post, apparently. I tried everything you suggested already and they didn't work. I still get the error when trying an inplace upgrade to resolve update issues.

Method 1: Burn at slowest speed, etc. I tried that already (see item 1 & 2 in my post).

Method 2:

Step 1: Upgrade Advisor. Tried that already (see item 3 in my post)

Step 2: Updated drivers. Not listed in post but 1st thing done after fresh install (see item 5 in my post).

Step 3: Clean boot with flat install. Did that (see item 7 in my post)

Any other suggestions would be greatly appreciated. Cheers!

Hello mp1005,

What is the reason for the Inplace Upgrade? What kind of issues are you trying to resolve?

A couple of things to suggest:
On the DVD, right click the setup file and select Run as Administrator.

If you downloaded using a download manager, try to copy without the download manager.

Let us know if this helps.

I was trying to do an inplace upgrade to resolve problems with Windows Update.  All of the trivial solutions have been tried already and downloading with and without the download manager was the first trivial solution I tried (see item 1 in my post) and that didn't resolve the problem. The issue is still not resolved as sometimes Windows Update works but most of the time it doesn't.  Some updates can be more troublesome than others and it can take 3 or 4 tries before a particular update is successfully downloaded and installed.  

Hi,

Method 1:

I would suggest you to perform clean boot and check.

Place the computer in a clean boot state and then check if it helps. You can start Windows by using a minimal set of drivers and startup programs. This kind of startup is known as a "clean boot." A clean boot helps eliminate software conflicts.
