Unable to install due to invalid digital certificate error

In case you are operating an outdated and unsupported version of the Windows operating system, it is highly possible that the root certificate on your Windows may no longer be valid or up-to-date. As a result, the certificate authority will not be able to authenticate the software.

Entrust is the entity that issues the digital certificate used by EscSoft, and it is crucial to ensure that your Windows installation is up to date with the latest Windows Update to enable the certificate to function effectively.

If you happen to be using an obsolete and unsupported version of Windows that lacks recent updates such as Windows 7, you may encounter this particular error. To troubleshoot this, you need to acquire and install the most recent updates from LegacyUpdate.net.
