= URL to download is invalid = When you purchase ePublisher products or request upgrades, you will receive an email containing the URL from which to download your ePublisher installation files. This link is only active for a week or two; it is changed often for security reasons. If you require a new installation file (for example, if you have reinstalled an operating system or you are moving your installation to a new computer), you may request the latest download URL by submitting a support request. We will verify your eligibility (you must have a valid ePublisher license for the requested version), and then we will gladly provide a new link to the necessary install files. ---- CategorySolutionsInstallation
