[SR] Error: 'LumionShellEx.dll'

1. Question:

1.1 While installing Lumion, the user constantly gets the "LumionShellEx.dll" error

2. Standard Reply:

2.1 Answer:

Hello

Thanks for contacting us. I'm sorry to see that you're having trouble installing Lumion.

The error you're seeing is either caused by insufficient Windows User Account permissions or by overzealous anti-virus software. In other words, it's not caused by the Lumion installer but by something on your PC.

If you click on 'ignore' Lumion will still work fine but double-clicking or right-clicking on '.LS' files won't work as expected.

If you right-click on an '.LS' file, choose 'Open with...' and select 'Lumion 10' with 'Always use this app to open '.LS' files' ticked, it will ensure that double-clicking or right-clicking on '.LS' files work as expected.

For more information, please refer to the article below:

Knowledge Base: How do you fix a "RegSvr32 failed with exit code 0x3" error when Installing Lumion?

Let us know if you've got any other questions.

3. Cause/Background information:

3.1 Reference Case: Staff Dojo Training

3.2 Technical Info:

ShellEx manages context menu entries when you right-click or double-click on '.LS10' Project files. Windows and/or your anti-virus software is not letting Lumion add those entries to the Windows Registry.
