Uncessful installation of Revit 2016. Error 1618

[ferries]

Hello,

My installation of Revit 2016 failed (error 1618). See the attached log file.

On my computer, Revit 2014 and 2015 have been installed.

They function correctly except a problem to export IFC files with Revit 2015 (I have already contacted Angel Velez).

Thanks in advance for your help.

Hi ferries,

Error 1618 means that there is already another installation in progress. Try to close out that other installer or reboot and try again.

Right.

Normally, The system is running Windows Update program background. SO it prevent your installation.
