1. Windows Updates
2. Sending and Receiving emails in Outlook
3. Connecting to a Printer

This article will explore each of these scenarios in detail, offering step-by-step solutions to resolve the 0x8007007E error and restore your system’s functionality.

Resolving Windows Update Error 0x8007007E¶

The Windows Update error code 0x8007007E typically signifies an issue with update synchronization within your Windows 11 or Windows 10 environment. This problem can manifest in both standalone computers and those integrated into an enterprise network managed by Windows Server Update Services (WSUS).

Microsoft identifies that this error often stems from a lack of hotfix installation prior to update synchronization. Specifically, the CopyToCache operation fails on client machines that have already downloaded the upgrade. This failure is attributed to corrupted metadata related to the upgrade within the WSUS environment.

To rectify this, repairing the Windows Server Update Services is crucial. In enterprise environments with multiple WSUS servers, this repair process should be replicated across each server, or selectively applied to servers that synchronized metadata before the hotfix installation. IT professionals can leverage WSUS logs, accessible through the WSUS admin console or API, to ascertain the metadata synchronization status and pinpoint affected servers.

Check if the error is resolved when running Outlook as administrator. If this resolves the issue, you may need to adjust user permissions or investigate further why administrator privileges are required for Outlook to function correctly.

Resolving Printer Error 0x8007007E¶

Error 0x8007007E can also arise when a client machine attempts to connect to a remote printer in a server-client environment. The error message often accompanying this issue is: “The specified module could not be found.” This scenario typically occurs when there is an incompatibility between printer drivers on the server and client machines, particularly concerning 32-bit and 64-bit architectures.

The problem arises when a 32-bit universal printer driver is installed on the print server. This installation creates a specific registry entry that informs client machines that a particular DLL file is necessary for printer functionality on the client side.

However, if the client machine is a 64-bit system, it requires a 64-bit version of the printer driver. Due to the registry entry created by the 32-bit driver installation on the server, the 64-bit client is incorrectly directed to use the 32-bit driver, resulting in the 0x8007007E error.

The problematic registry entry on the print server is located at:

HKLM\SYSTEM\CurrentControlSet\Control\Print\Printers\<printer name>\CopyFiles\BIDI

Solution: Deleting the BIDI Registry Key¶

To resolve the printer error 0x8007007E in this scenario, the solution is to delete the BIDI registry key on the print server. Removing this key prevents the server from incorrectly instructing 64-bit clients to use the 32-bit driver.

Steps to Delete the BIDI Registry Key:

Caution: Modifying the Windows Registry incorrectly can cause serious system problems. Back up your registry before making any changes. Proceed with caution.

1. Open Registry Editor: Press Win + R, type regedit, and press Enter to open the Registry Editor.

2. Navigate to the Key: In the Registry Editor, navigate to the following path using the left-hand pane:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Printers\<printer name>\CopyFiles

   • Replace <printer name> with the actual name of the printer experiencing the issue.

3. Delete the BIDI Key: Locate the BIDI key under the CopyFiles key. Right-click on the BIDI key and select Delete.

4. Confirm Deletion: Confirm the deletion when prompted by clicking Yes.
5. Restart Print Spooler Service (Optional): While not always necessary, restarting the Print Spooler service on the server can ensure the changes take effect immediately.
   • Press Win + R, type services.msc, and press Enter.
   • Locate the Print Spooler service.
   • Right-click on Print Spooler and select Restart.

After deleting the BIDI registry key, 64-bit client machines connecting to the printer will no longer be incorrectly directed to use the 32-bit driver, resolving the 0x8007007E error.

By implementing these solutions tailored to each scenario, you should be able to effectively resolve the error code 0x8007007E on your Windows computer, whether it arises during Windows Updates, Outlook operations, or printer connections.
