  • never used it but we have run into other poorly written products that will not upgrade over the top of current. In that case we created a 2 step update batch. the first step we silently uninstalled the old software, for the second step we installed the new software.

    start /wait MsiExec.exe /X{90BA08F7-C728-469C-8A35-BFBD3633BE08} /qn /norestart
    start /wait msiexec /i newversion.msi /qn
