The error code we provided, 0x0000066A, translates to ERROR_PATCH_TARGET_NOT_FOUND. This error message indicates an issue during program update or installation using a patch package. It signifies that the patch cannot locate the program it’s intended to update.

Here’s a breakdown of the issue and troubleshooting steps to address the ERROR_PATCH_TARGET_NOT_FOUND error:

Understanding Missing Patch Target:

• Patch packages are designed to update specific programs. The ERROR_PATCH_TARGET_NOT_FOUND error occurs when the patch cannot find the program it’s supposed to modify or update on your system.

Reasons Behind ERROR_PATCH_TARGET_NOT_FOUND:

There are a couple of reasons why you might encounter this error:

• Incorrect Patch for Program: You might be trying to use a patch designed for a different program altogether. Ensure the patch is compatible with the specific program you’re trying to update.
• Program Not Installed: The program targeted by the patch might not be installed on your system. The patch expects to find the program files to apply the updates.
• Incorrect Program Location: In rare cases, the program you’re trying to update might be installed in a non-standard location that the patch isn’t configured to look for.

Resolving ERROR_PATCH_TARGET_NOT_FOUND:

1. Verify Patch Compatibility:

   • Double-check the patch information (release notes, software vendor website) to ensure it’s compatible with the program you’re trying to update. Make sure you have the correct patch for the specific program.

2. Confirm Program Installation:

   • Verify that the program targeted by the patch is actually installed on your system. You can check through the Control Panel (or Settings app in newer Windows versions) in the “Programs and Features” or “Apps & features” section.

3. Check Program Location (if applicable):

   • If you know the program is installed but suspect a non-standard location, consult the software vendor’s documentation or website to see if they provide instructions for specifying the program’s location for patch application (not recommended unless necessary due to potential complexities).

4. Software Vendor Support:

   • If you’re unsure about compatible patches or encounter issues identifying the target program, contact the software vendor’s support for assistance. They can guide you to the appropriate patch and troubleshoot any specific issues related to the program’s installation or location.

Additional Tips:

• Some software vendors offer automatic update checkers that can identify the correct patch for your installed program version. Look for such options within the program itself or on the software vendor’s website.
• If you’re unsure about modifying program locations for patch application, it’s generally safer to reinstall the program altogether to ensure a clean installation and avoid potential compatibility issues.

By understanding the reasons behind the ERROR_PATCH_TARGET_NOT_FOUND error, you can identify the missing program or incompatibility issue. Verifying patch compatibility, confirming program installation, checking program location (with caution), and consulting software vendor support are the recommended steps to address this error.
