Destination Folder Access Denied

[Guest]

Vista is reporting that the file stdole32.tlb is corrupt.

I have attempted to copy a known good version to C:\WINDOWS\System32 but am
obtaining a "Destination Folder Access Denied. You need permission to perform
this action" error message, even with UAC switched off.

I would appreciate advice how to obtain the permissions to effect this repair.

TIA

This is a file that the system can repair. Try this:

Right-click on Command Prompt, and choose Run as Administrator. In the
Command Prompt window, type:

sfc /scannow

After the System File Checker scan, which may take awhile, you can confirm
any repairs by looking at the cbs.log (towards the end of the log) in
C:\Windows\Logs\CBS.

Thanks for the response.

Unfortunately this reported " Windows Resource Protection did not find any
integrity violations", but Windows still grumbles that the file is corrupt.

What I was really asking is how can a file be copied to WINDOWS\System32
without it being blocked.

At an elevated command prompt, type the following command, and then
press ENTER:

takeown /f Path_And_File_Name

For example, type
takeown /f E:\windows\system32\jscript.dll.

Type the following command, and then press ENTER to grant
administrators full access to the file:

icacls Path_And_File_Name /GRANT ADMINISTRATORS:F

For example, type
icacls E:\windows\system32\jscript.dll /grant administrators:F.

Type the following command to replace the file with a known good copy
of the file:

Copy Path_And_File_Name_Of_Source_File
Path_And_File_Name_Of_Destination

For example,
type copy E:\temp\jscript.dll E:\windows\system32\jscript.dll.

Thanks for your continued interest in this issue.

However, the problem is not with file access permissions but with Vista
blocking the file copy process.

Vista is blocking the copy because it won't allow a file owned by
TrustedInstaller to be moved/replaced. See:
