    Windows 10; HP error 1721

    Nope, Andre, I'm afraid Error 1721 is still very much there. I've got rid of everything on that list on your post except the Protect Tools Device Access Manager, which stubbornly doesn't want to leave me, even though I've informed it on innumerable occasions
    that I want it to move on and bother someone else. It merely says "Error 1721", which I suppose is the computer equivalent of sticking out its tongue.
     
  3. 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.
