Cadence Allegro and OrCAD 17.2-2016 Installation Guide for Windows April 2016 73 Product Version 17.2-2016 © 1999-2018 All Rights Reserved. Performing Special Tasks Updating the Products Hotfix Update Information Hotfixes are made available periodically after a main release ships. These typically contain bug fixes and minor performance or functional enhancements based on the current main release. The Cadence software update process works on an "as-requested" model. You must subscribe in order to be alerted about an update. Under this process, you will receive an email when selected product updates are available. These emails will contain a link to an online order form. When you are ready to receive and install the release, complete and submit your order. Note: You must have a current maintenance agreement to be eligible for software updates. Backup Hotfix You can enable backup option while installing HotFix. This option needs to be enabled for every installation. If you enable this option for an installation, then you can uninstall the complete installation or rollback the last HotFix that was installed. Rollback is possible for the last two installed HotFixes in sequence, provided backup is enabled for both the installations. For example, you installed three hotfixes with backup enabled: hotfix1, hotfix2, and hotfix3. You can only rollback hotfix3 and hotfix2, and not hotfix1. Note that if you did not select backup in the current installation, rollback will not be available even if the last installation was with backup enabled. For example, you installed hotfix1 with backup on and then installed hotfix2 with backup off. Later on, if you install hotfix3 with backup on, you can only rollback hotfix3. Note: You can use Programs and Features of the Windows Control Panel to uninstall. In Programs and Features, select the Cadence Allegro and OrCAD release and click Uninstall. The uninstall process lets you select between HotFIx and full release uninstall. To install HotFix in silent mode with backup on:
