    Error 1721 in Windows 10. Error 1721: 'There is a problem with this Windows Installer package. A program required for this install to complete could not be run.' during installation/uninstallation

    Hello,

    I have been trying to install "CSI Etabs 2013 software" . but I got this Error (1721) and then when I want to Uninstalling , i got this Error(1721) again.

    I did this steps but didn't work.

    • Hold down the Windows key + R to open the Run box
    • Type MSIEXEC /UNREGISTER and click OK Even if you do this correctly,it may look like nothing happens
    • Type MSIEXEC /REGSERVER and click OK
    • Try the installation once more
    By the way, I don't have problem with Installing last version of softwares. but I always have problem with Installing old version of softwares.

    Best regards.
