how to run WixSilentExecCmdLine to run batfil ein background

Question

I am trying to run a bat file in background while installing an app using WIX. For this I used WixSilentExecCmdLine but after writing this code sniphet Installationitself failed.

<Property Id="WixSilentExecCmdLine" Value="C:\SampleWix\myBat.bat" Hidden="yes"/>
<CustomAction Id="SilentExecExample" BinaryKey="WixCA" DllEntry="WixSilentExec" Execute="immediate" Return="check"/>

<InstallExecuteSequence>
    <Custom Action="SilentExecExample" Before="InstallFinalize"/>
</InstallExecuteSequence>

Light Command

    %WIX_LIGHT% %INSTALLER_BUILD_DIR%\*.wixobj -o %OUTPUT_DIR%\%MSI_OUTPUT_FILE_NAME% -ext WixUIExtension -ext WixUtilExtension.dll

Answer 1

You will not be able to run another parallel install while in the ExecuteSequence. Windows installer has a limitation that only one install can be in the ExecuteSequence at one time.
