You attempt to uninstall the WSS Agent (WSSA) application from Windows by using Add/Remove Programs but receive a message that a newer version of the program has already been installed.
Command line uninstallation attempts also fail, such as:
msiexec /x {4102C9CD-C185-404E-B821-673E9FEE9D30}
What are the Windows WSSA Package Versions (Product Codes)?
From the command line, use the msiexec command to generate an uninstall log.
EXAMPLE:
Example using a recent WSSA .msi install file:
NOTE: The /L*V parameter generates a verbose log.
This generated a debug log.
From this debug log, we see that the correct ProductCode to use for the command line uninstall is:
{216652C2-709F-449B-B92F-9723C7E78384}
Re-attempt the uninstall with this correct code.
OPTIONAL PARAMETERS:
msiexec /x {216652C2-709F-449B-B92F-9723C7E78384} /quiet UNINSTALL_TOKEN=password
