[TR] 3.1 How to solve typical download problems (UNDER REVIEW)

The Lumion downloader and installer was unified into a single executable file in Lumion 12.3 so this article will be split into two sections:

1. Lumion 12.3 and newer versions:

Same as in older versions, download problems are most of the time related to overzealous security software interfering with the Installer. However, the new Installer now logs extra information (new error messages) that can help us troubleshoot issues

This is the go-to article to troubleshoot download issues:

Here's a list of all the possible error messages plus an issue tracker (staff only)

 

Whenever a user reports a download problem, the first step is to request the logfile.txt that is located in the same folder where the Installer is. That log will provide valuable info that can help identify what is going wrong and why the download is failing.

 

2. Lumion 12.0.2 and older versions:

This is what the Lumion 11-12 Download Manager looks like:

The old Download Manager:

Troubleshooting:

1. Almost all of the download problems occur because something on the users' PC is preventing the Download Manager from contacting the license server or from writing files to the hard-drive.

 

The culprit is usually overzealous firewall/anti-virus/security software or lack of write permissions.

 

An extreme case where trying all other suggestions failed is in this ticket:

However, even then the solution is still covered by our main article (below).

In this case, changing the download to a different network then worked.  It's a last option if nothing else works, and if you find you are not making progress with all the prior steps then you need to start the user considering and trying this final option (so long as that other network is also not restrictive, of course).

 

If the Download Manager does not start downloading Lumion, gets stuck, or displays an error message (for example "Access denied"), the following checklist will resolve 99.9% of all problems:

 

2. Error: ‘Access is denied’.

 

3. Error: ‘The license may be invalid or the download manager is outdated. Re-download it from the latest download e-mail.’

 

4. Local download speed issues. 

5. Last options to consider:

6. Unusual but does happen but rare and now the DLM also checks for minimum drivers and should report such (added notes to current 2022 changes to DLM/Installer): 

"I didn’t install the GPU drivers and after that it worked..."

Notes:

1. Why might antivirus software prevent files from downloading:
