In Wix installer InstallCondition and InstallCommand do not work correctly together

Question

We have 3 different parts of our application, part 1 can be installed and used as a standalone application as well. Part 2 and Part 3 communicate with Part 1. So, part 2 and part 3 installers contain part 1 as a dependency. Some user may have part 1 already installed. If user does not have part 1 installed and is trying to install part 2 or 3, the part 1 should be installed in quiet mode. Also, we need to make sure that the version that is installed should be the same version as current installation or a newer one. So, I found InstallCondition and DetectCondition to detect the existing installation of part 1.

Now, I have been facing an issue that when I set DetectCondition and InstallCondition, the InstallCommand is not passed to the ExePackage and it is displayed to the user to install manually. Although, I have passed "/q" in the InstallCommand,

<util:RegistrySearch Id='CheckCCClientVersion' Root="HKCU" Key="Software\Organization\MyProduct" Value="Version" Win64="no" Result='value' Variable='EXISTINGCLIENTVERSION'  />
<util:RegistrySearch Id='CheckCCClientExists' Root="HKCU" Key="Software\Organization\MyProduct" Value="Version" Win64="no" Result='exists' Variable='CHECKCLIENTEXISTS' />

    <Chain>
        <ExePackage Id="Product1Id" SourceFile="$(var.ClientBundlePath)" Compressed="yes" Permanent="no" PerMachine="no"
                    DisplayName="Product Display Name" DetectCondition="CHECKCLIENTEXISTS" InstallCommand=" /q /norestart" InstallCondition="EXISTINGCLIENTVERSION >= v$(var.Version)" UninstallCommand="/q /norestart"/>

        <MsiPackage Id="MainProductId" Visible="no" EnableFeatureSelection="no" Description="Required Files."
                    SourceFile="$(var.AddinsMsiPath)"/>
    </Chain>
</Bundle>

I have tried adding and removing space character in the start of InstallCommand but with no luck. Any suggestions or ideas would be appreciated in this regards.

PS: WiX Toolset v3.11.2.4516 is installed on build servers and same is installed on my machine.

Make your DetectCondition what you currently have for InstallCondition, then remove InstallCondition. DetectCondition should detect the desired version (or higher). If it's false, Burn will install it.
