Unable to find or download Insight Lighting Analysis for Revit 2021

[m-hinz]

I've been looking all over for a way to download Lighting Analysis for Revit 2021 for like 2 hours and can't for the life of me get it to work.

I've been told that Lighting analysis is included in Revit 2021 and I've been told it's an extension I'm required to download, But that option just doesn't exist for Revit 2021.

For the love of all that which is holy, can someone here tell me what I'm doing wwong.

I don't know the 2021 stuff, but it is harder to find the download files for Revit of a certain age (I think 3 versions back?). I assume the same is true for extensions. Were you on subscription back then? If not, you may not be eligible to download it now. You may have to contact Autodesk. Or get a newer version.

I have multiple versions of Revit, including 2023, but the client we're working for requires us to use 2021. I sent an email to Autodesk support so I guess I'm just SOL for the next day or two.

I got curious, but it looks like it was superseded by "insight". At least that is where it routed me. It wasn't clear for what version of Revit this is

Autodesk has a habit of discontinuing such add-ins or features. Hope they even had a 2021 version. For some reason i think to have read insight will be superceded by the new carbon feature. That is why I don't bother learning new Autodesk tools......

As i know, Autodesk starting to move the updates/plugins to manage.autodesk.com per version 2022 and above. You can check the previous version (example: 2021), within the Autodesk Access App.

Try checking there too

The way I understand it is, the current licensing structure includes the Current version, +3, +2 unsupported. 2020 and 2021 fall under the Unsupported currently. I noticed that right after 2025 came out most/all the 2021 content (downloads, updates, service pack, etc....) were removed from the products and services page. Unless a policy changes, when 2026 comes out in a couple months, 2020 will be unlicensed and 2021-2022 will be unsupported. I assume that all the 2022 content will be removed at that point too.

They claim you can request older legacy versions, but we tried that when this policy first started and were not able to get anything older than the 6 versions that were currently "available" (current +3, +2).
