The various upgrade components available on Apteryx's upgrade web pages will automatically find and upgrade XrayVision® (XV) and its components. During the upgrade of various XV components, backups are automatically generated that can be used to downgrade in the event of failure of the new component.
Each time XV is started, it automatically checks the computer environment to try to detect incompatible DLLs and extension components. Should any incompatible components be detected, XV will display a dialog indicating which components are conflicting and give the user the option of continuing with execution of the application or quitting the application.
Typically when the user chooses to continue with the execution of the program, the application crashes. Should incompatible components be detected, record the conflicting components and either update them from Apteryx's upgrade web site or simply delete the component if it's not needed.
Components that have been upgraded utilizing Apteryx's various upgrade programs can be downgraded should the new component cause problems. Before components can be downgraded, the AppDowngrader.exe application must be located in the XV application directory. If this application does not exist in the main application diectory, go to http://www.apteryx.com/software-updates. Find and click XV Downgrader Application link to download and run the installer.
To downgrade components:
Navigate to the XV application directory.
Double-click to run the AppDowngrader.exe application.
Select the component that is to be downgraded and then click on the Downgrade button.
The new release of the component is not deleted but is backed up just like an
upgraded component. The next time you run the downgrader program, you will see
the new component listed as one of the downgrades even though it is in effect
an upgrade.
