Re: [WiX-users] performance counters are not being uninstalled

That is exactly what it means. You could identify the other product using a
component with the same GUID and either remove or repair it.


A vbs/js script using the Installer.ComponentClients property would tell you
all the clients (by ProductCode) currently registering components with your
same GUID (you pass to the property the component's GUID -- that is not
clear on the MSDN page).

        WScript.Echo("JScript");
        var Installer = WScript.CreateObject("WindowsInstaller.Installer");
        var products =
Installer.ComponentClients("{9B102980-0606-4656-AADE-B277402D7359}");
        for (var i = 0; i < products.Count; ++i )
        {
            WScript.Echo(products.Item(i));
        }
        products =
Installer.ComponentClients("{C20FBE98-FEE7-4C46-8617-73C60D2C7CC2}");
        for (var i = 0; i < products.Count; ++i )
        {
            WScript.Echo(products.Item(i));
        }

Thanks for the response.  Here is what I found in the verbose uninstall log.
The guids match the guids for my performance counter components in wix.  I
assume the message means that some other program or component on the
computer is referencing the performance counters, causing them to remain
installed.  Is that correct?  Is there any way in WIX to override this
feature and force them to uninstall?

When uninstalling, what does a verbose log say about the states of the
perfCounters component (look around CostFinalize in the log).

Subject: [WiX-users] performance counters are not being uninstalled

I have a wix project that installs performance counters using the
util:PerformanceCategory and util:PerformanceCounter elements.  The
performance counters are installed as expected.  However, when uninstalling,
the performance counters are sometimes left installed on the machine.

Here is an example of the pattern we are using:

<Component Id='perfCounters' Guid='C0D623E8-F04C-48A7-9F2D-5F996891AE24'
KeyPath='yes'>
        <util:PerformanceCategory Id="PerfCounterCategory"
Name="ProductPerfCounters" MultiInstance="yes">

          <util:PerformanceCounter Name="Requests per second"
Type="rateOfCountsPerSecond64" />
          <util:PerformanceCounter Name="Request count"
Type="numberOfItems64" />

        </util:PerformanceCategory>
      </Component>

Does anyone know why the performance counters are left installed sometimes?
Is there a way to 'force' them to be uninstalled using wix?
