This guide explains how to use the myQNX License Manager and the QNX Software Center. It is intended for corporate buyers, development managers, and IT administrators who need to manage QNX product licenses, and for developers who need to install and maintain QNX software on their development hosts.
Using the QNX Software Center
The QNX Software Center provides a secure, efficient way to discover, install, and manage software products distributed by QNX. It replaces traditional command-line procedures with a graphical user interface that takes the guesswork out of managing product dependencies. It also lets you create patch sets: specific configurations of QNX products, patches, and updates that enable development teams to reproduce issues and standardize on the same software base.
Downgrade a package to a previous version
The QNX Software Center allows you to downgrade an installed package to a previous version.

It replaces traditional command-line procedures with a graphical user interface that takes the guesswork out of managing product dependencies. It also lets you create patch sets: specific configurations of QNX products, patches, and updates that enable development teams to reproduce issues and standardize on the same software base.
    - View your registered products
      Before you begin using the QNX Software Center, visit your myQNX account profile to view the products that have been deployed to you. The profile includes a Registered Products section, which shows at a glance the license key, serial number, license certificate, and license administrators for each deployed product. If the products you need to install don’t appear in your profile, contact your license administrator.
    - Install and launch the QNX Software Center
      To install the QNX Software Development Platform (SDP) 7.* and any of its associated packages, you must first install the QNX Software Center onto your workstation.
    - Install the QNX Software Development Platform
      After you log in, the QNX Software Center displays a Welcome screen that lets you install the QNX Software Development Platform (SDP) and other QNX products.
    - Add, choose, or remove installations
      The QNX Software Center lets you create and maintain multiple installations of the QNX Software Development Platform (SDP) on your workstation. Each installation serves as a container for a set of QNX software packages, and each lives in its own directory, where you can modify it independently of any other installation. For instance, you can create one installation for production purposes, another for experimental purposes, and so on. You can install copies of the same addon package in multiple installations.
    - Advanced installations
    - Install the QNX Momentics IDE
      If you intend to develop applications for the QNX OS, we recommend that you install the QNX Momentics IDE. The IDE extends the capabilities of the QNX Software Development Platform (SDP) by providing a graphical environment for developing, debugging, and profiling applications.
    - Get to know the QNX Software Center’s user interface
      After you install the QNX Software Development Platform (SDP), you see the main screen of the QNX Software Center.
    - Manage Your Product Licenses
      To activate or deactivate your product license, it's always best to use the QNX Software Center (QSC). If, for some reason, you are unable to use QSC, both processes can be completed from your myQNX account profile.
    - Inspect package and file properties
      Using the QNX Software Center, you can inspect the properties of any package or file available for, or deployed in, an installation.
    - Edit installation properties
      The Edit Installation Properties dialog helps you control which packages will be added to your installations. You can change these properties at any time; you can also assign a different set of properties to each installation. For instance, you can assign one set of properties to an installation used for production purposes, and another set of properties to an installation used for experimental purposes.
    - Group by
      The Group by action allows users to group Available packages by Download Center Folder or Release.
    - Read the package release notes
      If a software package has release notes, you can access the notes through the QNX Software Center, either before or after you install the package.
    - View the end user license agreement
      If a software package has an end user license agreement, you can access it through the QNX Software Center (QSC). The end user license is displayed as part of the package properties. For more information about viewing package properties, go to inspect package and file properties. If the end user license agreement section of the package properties doesn't contain the full text agreement with a link, then you can use the following procedures.
    - Email notifications
      Subscribe to receive email notifications regarding new package updates or customer notifications.
    - Install addon packages
      Once you’ve installed the QNX Software Development Platform (SDP), you have a complete environment for developing programs that run on the QNX OS. The environment includes the QNX Momentics IDE and a rich suite of command-line tools. To run programs on QNX OS, you need to install addon packages, such as a reference image (for instance, a virtual machine for VMware) or a board support package (BSP) for your target system.
    - Install debug symbols
      Many packages include debug symbols. To install the debug symbols for a package, you install the package first. You can then install some or all of its debug symbols.
    - Install updates
      The QNX Software Center automatically displays product updates that you are entitled to.
    - Downgrade a package to a previous version
      The QNX Software Center allows you to downgrade an installed package to a previous version.
    - Uninstall packages
      The QNX Software Center lets you uninstall packages that you have added to an installation.
    - Filter packages
    - Work offline
      If you are developing on a workstation that has no Internet connection, you can still use the QNX Software Center in offline mode. You can, for example, import a new installation from a locally mounted package archive. You can also install addons and updates that were included in your import, and work with patch sets. However, the QNX Software Center won’t be able to notify you of newer updates from QNX.
  - QNX Software Center Advanced Topics
    This chapter guides you through tasks that you may have to perform only on occasion. It also discusses how to address potential connectivity or license activation issues.

Downgrade a package to a previous version

The QNX Software Center allows you to downgrade an installed package to a previous version.

Downgrading a package removes all files that belong to the package and replaces them with files from a previous version of package. It also removes any files added to the package.

To downgrade an installed package:

Go to the Installed tab, then right-click the package and select Downgrade.

The QNX Software Center calculates system requirements and displays an Available Updates dialog.
Make sure that the package version you want to install is checked, then click Next.
Review the list of packages that the QNX Software Center will install, then click Finish.
When installation is complete, you'll see the downgraded package in the Installed tab.

Note:

You cannot a downgrade a package to a previous version if other installed packages depend on the existing and more recent version.
