Certificate validation failed because of outdated root certificate

Question / Problem

Every time I try to install or run the application, I get an error message "Could not validate software certificate." with an error code -2146762487.

How can I resolve this error?

Answer / Solution

This error code indicates that the root certificate is not trusted on the system. We just recently updated the certificate we used to sign our applications, so it still seems to be the case that this root certificate is not yet up to date.

These certificates are usually being updated and installed online and/or along with Windows updates. These updates might be disabled manually though.

Please check for pending or available Windows updates first.

If this doesn't work, please try to download and install the updated certificates manually. They are issued from GlobalSign and should therefore be considered safe:

Root certificate https://secure.globalsign.com/cacert/codesigningrootr45.crt

Intermediate certificate https://secure.globalsign.com/cacert/gsgccr45evcodesignca2020.crt

Please ensure to install the root certificate to the correct store (root certificates). Having Windows select the store automatically, it might select the wrong store for this certificate.

To install the root certificate, proceed as follows:

  1. Download the certificate. If the browser reports that the file could damage the system, confirm this message with "Keep".
    As the certificate comes from a trusted source (GlobalSign), this warning is not relevant in this case.
  2. Right-click on file and select "Install certificate" in the context menu.
  3. A Windows dialog opens. First select the storage location "Local computer" and "Next".
  4. On the following page, select "Save all certificates in the following location" -> Browse -> "Trusted root certification authorities" for this certificate.
  5. Click on continue/next until the import process is complete.

Proceed in the same way to install the intermediate certificate, but select the "Intermediate certification authorities" folder in step 4.
