Elements Endpoint Protection Software Updater fails to install third-party application update due to ”Failed to validate downloaded file” error

Issue:

Elements Endpoint Protection Software Updater fails to install third-party application update due to "Failed to validate downloaded file" error

Example update installations that show this installation status: 

• 7-zip 

Resolution:

The error "Failed to validate downloaded file" is caused by the "install only signed updates" setting in the Elements profile. If the update is not signed, installation will fail if this setting is enabled. 

Follow this guide to allow to download and install unsigned third-party application updates:

1. Log on to the Elements Security Center portal
2. Click the Security configurations > Profiles tab
3. Edit the current profile in use on the problematic devices
4. Go to the Software Updater settings page
5. Disable the 'Install only signed updates' option
6. Click Save profile

Now try reproduce the issue by sending a software updater install operation to install the same updates to the devices from the Element Security Center portal.
