DirectX 9.0 "Cannot Copy File"

Archived from groups: microsoft.public.windowsxp.configuration_manage (More info?)

I would try reinstalling DirectX 8.1 to see if that will
work. Then try the 9.0b isntall again.

If that doesn't work, try these tricks:
"dx90b_redist.exe" is the name of the full DirectX
package. You can extract the files with this command:
dx90b_redist /C /T:C:\DirectX9b
So this will extract to a folder on C: named "\DirectX9b".
Go into that folder and try using MSIEXEC commands.

The MSI package for DirectX is "mdxredist.msi". So type
the following to force a reinstall:
mdxredist.msi /fa

To uninstall, try this:
mdxredist.msi /x

Not sure, but some of the pre-9.0b vulnerabilities might
have caused your situation:

installation. ERROR: Cannot Copy File. I have tried
downloading DirectX from microsoft website, and I have
tried 2 CD's with DirectX 9.0b installation. All of them
give me the same problem. Does anyone know what causes
this error. Found a small description on my problem in
the Microsoft Knowledge Base but all it says is that the
DirectX installation files are corrupt.. find another
installation source. (I apologize about being so vague on
the error description.. not at problem PC at the moment..
can repost more information as needed)
>I also noticed that in DxDiag.. it gives me an
indication that files are missing upon starting DxDiag.
It shows version 8.1 and has files listed as "missing"
under the DirectX Files tab. It also fails the 3D display
tests.
