During the installation of SmartConnect 21, the following error message appears, especially when you cannot find “eOne SmartConnect” under Control Panel > Add/Remove Programs to uninstall the existing version.
“Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the control panel.”
Causes
- The “Uninstall” function is not functioning properly in Programs and Features.
- Corrupt registry keys on 64-bit operating systems.
- Corrupt registry keys control the updated data.
- Prevent new programs from being installed.
Resolution:
You’ll need to locate any existing “eOne SmartConnect” references on the system, uninstall them using the steps below, and then try installing again with a new install.
Required: Log off all other users from the server/machine. Only you should remain logged in as admin.
- If you have the original SmartConnect installation files for the same version, open them and select Installer Files — this should give you the option to uninstall.
- Try uninstalling via Command Prompt or PowerShell using the command:
product where name="SmartConnect" call uninstall - Attempt to uninstall via Safe Mode.
