1. Here's how

When trying to download/save the Download Manager in older versions of Internet Explorer and Microsoft Edge, you may get an 'Access is denied' error.

The error is caused by a lack of Windows permissions or by overzealous anti-virus/security software.

1.1: To resolve the problem, please install all available Windows updates. Doing so will also update Internet Explorer and Microsoft Edge.

1.2: If the problem persists, please install Google Chrome or Firefox:

• External Link: Download Google Chrome
• External Link: Download Firefox

1.3: Go to your Lumion Account using Chrome or Firefox and then try to download the Installer.

• Knowledge Base: Download Lumion and Lumion Pro

1.4: You can uninstall Google Chrome/Firefox again when you have downloaded the Lumion Download Manager.
