# Patch Upload Failed Checksum Mismatch Last Updated On: 12 Oct 2026 3 minutes read ## Problem A manually uploaded third-party patch fails checksum validation. ## Cause The uploaded installer does not exactly match the package expected for the selected Patch ID, or the file is incomplete, corrupted, modified, or renamed. ## Verify the installer package 1. In the upload patch view, compare the expected patch or application, exact version, architecture, installer or package variant, filename, and file size with the file that you downloaded. Vendor pages can provide multiple installers with the same displayed version; only the exact package expected by the Patch ID passes checksum validation. 2. Open the downloaded file's properties and verify its original filename and version information. Do not rename the file. 3. If any value differs, download the expected package and upload it again. ![Patch upload view showing the expected installer details](https://www.manageengine.com/products/desktop-central/help/images/checksum1.png) ![Installer properties showing the original filename and version](https://www.manageengine.com/products/desktop-central/help/images/checksum2.png) ## Oracle Java packages For Oracle Java packages, select the JRE or JDK package, version, and architecture required by the Patch ID. For Java 8 on Windows, use the [Oracle Java SE downloads](https://www.oracle.com/java/technologies/downloads/#java8-windows) page. After signing in to the vendor site, retain the original installer filename. 1. Click **Upload** next to the upload-failed message and upload the expected package. 2. Alternatively, open **Patches → Downloaded Patches → Upload Patches**, search for the application Bulletin ID, and click **Upload** under Action. Oracle application Bulletin IDs include JRE 6: `TU-011`, JRE 7: `TU-030`, JRE 8: `TU-053`, JDK 8: `TU-160`, JDK 11: `TU-802`, JDK 13: `TU-1000`, JDK 14: `TU-1139`, and JRE 8 for Mac: `MAC-033`. ## Related - [Troubleshoot patch download failures](https://www.manageengine.com/vulnerability-management/kb/patch-management/patch-download-failures.html)
