Welcome to the Lumion forum
Sorry to see you are having installation problems. This is a rare case, and we have not yet been able to fully identify why that has happened to a few customers, other than it happens from the download.
Attach a screencapture of the downloaded installation files, should look something like pic1 attached.
Please uninstall Lumion again using Windows Uninstall from the Control Panel.
If the file sizes do not match those in pic1, then you will need to download Lumion again, as there are one or more files not properly included in the download.
When Lumion installs, make sure Lumion installs to the \Program Files
folder, and not \Program Files (x86) (pic2).
It's also possible some AV, or other security or monitoring software, is blocking certain files from being correctly installed. What AV etc do you have on your PC? You can try turning those off to see if that helps with the install.
Would you please add your Lumion 5 license key to your forum Account (click here
