Error 1721

I was trying to install Final Draft on a new Lenovo Yoga, but the installation could not complete because of Error 1721. It says "There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor." Since the install was interrupted, I tried to uninstall the program to start over, but the same error box comes up whenever I try to uninstall the program. So now Final Draft won't open, but won't delete either. Can you help?

Thank you!

    It didn't work for me, any of the methods.  I am trying to install Final Draft 8 myself and Error 1721 continues.  When I attempt to uninstall, gives the same error.  Any help is appreciated.  Thanks.

    I too am having the same issue and Microsoft will not give me a clear answer about how to fix it! For me it is not just Final Draft but MOST programs I install! I am a professional writer and have already lost one day of work!  Please help!

    Did you ever find a solution? I'm trying to install FD9 on a new computer and keep getting the same error message.

    Thanks!

    By the way, on method 3, I am unable to set to Automatic by right-clicking on the properties.  This is a personal machine and not company owned or managed so I would think it should have worked but that ability is not highlighted for me.

    Right-click and select Properties, set the startup type to Automatic.
