Unfortunately it looks like all the files required in the download have not completed properly.
Please see attached example of files and file size you should have once the Download Manager (Lumion_3_2_1_Free_Download.exe) has completed.
Run the Download Manager again, as it verifies files and may continue to recover or download files. If not, then remove all files other than the Download Manager, and start the dl again.
Please check also that you have sufficient file space on the hard drive for the install: approx 1.3 GB
