Uninstall and Downgrade to the previous version

When you update an existing 4.0 SU or 2015 R1 or later system to the latest 20## R# release, the update install for each product component backs up the previously installed version. The backed-up files include the previously installed component's .msi plus any applied .msp files (4.0 SU or 2015 R1 or later patches), along with any transform (.mst) used during the original installation.

To uninstall the newly installed product version, for example, for troubleshooting purposes, you can choose to downgrade to (reinstall) the previously installed product version. Uninstall 2015 R1 or later and downgrade to the previous version using one of the following methods:

• Programs and Features
• Group policy deployment
• Interactive Update

Programs and Features

You can use Programs and Features in Control Panel to uninstall 2015 R1 or later product components and downgrade to the previously installed version on the CIC server, client workstations, and other servers on the PureConnect (CIC) system.

In Programs and Features, select the appropriate 2015 R1 or later product component and click Uninstall.

If there is a previous product backup available, a Confirm Previous Version Install dialog box gives you the choice to reinstall the previous version.

Note: When uninstalling and downgrading PureConnect (CIC) product components on the CIC server, uninstall and downgrade the CIC Server install component before uninstalling and downgrading the Interaction Firmware component and any Language Pack components.

Group Policy Deployment

When uninstalling 2015 R1 or later product components using group policy deployment, use the REINSTALL_BACKUP_PRODUCT property to downgrade to the previously installed version. For more information, see the Group Policy Deployment Technical Reference in the PureConnect Documentation Library.

Interactive Update

If you used Interactive Update to apply the 2015 R1 or later updates to client workstations, when you select a 2015 R1 or later component as "Remove" in Interactive Update Provider, the component downgrades to the previous version (if the previous version is present). For more information, see the Interactive Update Technical Reference in the PureConnect Documentation Library.

Note: To uninstall and downgrade Interactive Update Provider 2015 R1 or later to a previous version, use Programs and Features. You may need to restart IC Services after downgrading to a previous version of the provider.
