What is a Hotfix?

A Hotfix is a software package that you can install on an existing installation of our software. Each hotfix contains fixes for one or more known issues in our released software.

Because there is always a small chance for a hotfix to cause new issues, you should only install Recommended Hotfixes, unless otherwise instructed by your Esko Software Support team.
