Hi Shalini, thank you for the screenshot and the information.
I see what the problem is.

A file is missing which means that it was prevented from being downloaded or prevented from being installed by something on your PC (typically your anti-virus software).
The next step is to post a screenshot of the files that the Lumion
Download Manager downloaded to see if the file was allowed to be downloaded or not.
