2.1. Answer:

Hi,

Thank you for reaching out and sorry to hear about the issue.

When some buttons don't work, particularly the ones you mention, it probably means that Lumion is unable to open Windows Explorer. 

Are you using any remote access applications for Lumion? If so, please make sure they appear in the list below:

• Knowledge Base: Is Lumion compatible with remote desktop or cloud services?

Otherwise, there may be issues with the input, at the moment when attempting to open the Windows Explorer pop-up. If you are accessing the PC locally, please follow these steps:

1.1 Open a Lumion file through the button Load:

1.2 Select Load project..:

1.3 Choice a .LS file from Windows Explorer:

2. If it doesn't work, then it most likely means Windows does not register the command to open Explorer. A potential way to fix that would be by following the steps below:

 2.1 Run (as Administrator) the Windows Command Prompt and type in the following commands without the " ". (Note that they will only run if there are Administrator rights.)

• "sfc /scannow" then Enter. This command will scan all protected system files, and replace corrupted files with a new copy.
• "chkdsk /f" then Enter. This will get Windows to check (and fix) disk errors next time there's a boot. If it prompts to run upon reboot, type 'Y' and Enter.

2.2 Similarly, run Command Prompt as administrator. Then, type following the command lines:

• Dism /Online /Cleanup-Image /CheckHealth
• Dism /Online /Cleanup-Image /ScanHealth
• Dism /Online /Cleanup-Image /RestoreHealth

2.3 (IMPORTANT) Reboot the PC.

After Restarting the computer test if the button in Lumion works well now.

3. If the issue persists, it might be possible that an application on your PC is highjacking Lumion's ability to open Windows Explorer. The usual suspects in these cases are Quick Assist and JTB Process Monitor Client, so if you have them installed, please temporary disable them and try to render again.

4. If points 1 through 3 do not work, please forward us a System Information file so that we can try and identify another culprit:

Let us know how it goes.
