This post describes how to fix the error:

A file that is required cannot be installed because the cabinet file has an invalid digital signature. This may indicate that the cabinet file is corrupt.

Cause

This can occur when certificates from the cabinet file's digital signature certificate trust chain are missing and cannot be validated.  This can happen when you're running an installer in an environment that's not connected to the Internet and is therefore unable to update the trusted certificate authorities automatically.

Resolution

Right click the cabinet file, go to the Digital Signatures tab, press Details, then View Certificate and check the Certification Path.  This shows the certificates required to complete the trust chain.

Cabinet file digital signature certification path

Next, download and install any certificates that are missing from the trust chain.

This post describes how to fix the error "This app will now restart to free up more memory" which can occur when using apps such as Netflix on an LG TV after just a few minutes of use. Resolution To resolve the issue, unplug the TV then press the on/off button for 10 seconds.  Wait a further 20 seconds then plug the TV back in and turn it back on. Apps should now run without the error. Edit: The on/off button on my LG TV is directly under the standby light on the bottom of the TV. Edit: I didn't have to do this myself but one person who has left a comment said that clearing all browsing data worked for them.  I have written a post explaining how to do this: LG TV Clear All Browsing History Data . Edit: A few other people have also suggested turning off quick start in settings (and if it's already off, turn it on then off again).  I have written a post explaining how to do this: LG TV turn off Quick Start in settings Related Posts -  LG TV delete/remove/hide ch
