Yes. Many have done it before you. It is a terrible design but people still do it.

Subject: [wix-users] Run a batch script during Wix installer startup

We have below code which we use to run some basic commands at the very early stage of installer startup:

        <Property Id="WixQuietExecCmdLineTest" Value= '"net" use D: /DELETE /Y'/>
        <CustomAction Id="CA_DDriveAutofixTest" BinaryKey="WixCA" DllEntry="WixQuietExec" Execute="immediate" Return="ignore"/>
            <Custom Action="CA_DDriveAutofixTest" Before="FindRelatedProducts">NOT Installed</Custom>

But is it possible to run a .bat script using this method? The .bat script is already present on the system (installed by another installer already) in C:\<some folder>\. I just need to run it and decide whether to proceed with installation or to stop. Is that possible with Wix? This needs to happen at the earliest possible stage in the installer execution.
