You have the option of reverting the changes incorporated by the installation of a Service Pack. You can revert to the previous version of the Service Pack or to the base version of the application. Before you start the un-installation process, make sure no application is running.
The steps to revert to a previous version are as follows.
Start Update Manager: Run UpdateManager.bat/sh from <OpUtils Home>/bin directory.
Select the service pack, which needs to be uninstalled, from the Installed Service Pack list. Click the Uninstall button to proceed with the un-installation.
The list of dependent service packs if any will be shown for your confirmation before proceeding with the process. Click Finish button to proceed.
Thus the specified Service Pack is un-installed in the application. You can now continue with the screen (like un-installing another Service Pack) or quit the tool by clicking the Exit button.
