Cisco Bug: CSCsz67981 - MSI-based upgrade from CCA Agent 4.1.3 to 4.1.8 requires uninstall

Last Modified

Products (1)

  • Cisco NAC Appliance (Clean Access)

Known Affected Releases

4.1(8)

Description (partial)

Symptom:

Attempts to upgrade MSI-based Cisco Clean Access (CCA) Agents (that is, agents provided either
manually or via policy-based install rather than downloaded from the Server or Manager directly)
fails, producing an error of :

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.

This occurs even if the installation file is properly renamed to CCAAgent.msi prior to installation of
either 4.1.3 or 4.1.8 code (this renaming is a required step).

Conditions:

Issue does not affect agent upgrade when the Agent is downloaded directly from the Server or
Manager.

Possible other combinations are affected - only 4.1.3 to 4.1.8 was tested.
