Issue/Introduction

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to uninstall the WSS Agent (WSSA) application from Windows by using Add/Remove Programs but receive a message that a newer version of the program has already been installed.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)?

 

Resolution


From the command line, use the msiexec command to generate an uninstall log.

EXAMPLE: 

msiexec /x "c:\MyPackage\Example.msi" /L*V "c:\log\example.log"


Example using a recent WSSA .msi install file: 

msiexec /x "c:\temp\WinWSSAgentInstaller64-7.3.5.15179.msi" /L*V "c:\temp\example.log"


NOTE: The /L*V parameter generates a verbose log.

This generated a debug log.

Property(S): AI_NEWERPRODUCTFOUND = {216652C2-709F-449B-B92F-9723C7E78384}
Property(S): OM = **********
Property(S): ProductCode = {4102C9CD-C185-404E-B821-673E9FEE9D30}


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.

msiexec /x {216652C2-709F-449B-B92F-9723C7E78384}


OPTIONAL PARAMETERS:
msiexec /x {216652C2-709F-449B-B92F-9723C7E78384} /quiet UNINSTALL_TOKEN=password
