Add-ins not showing up

[jmartt]

Using (or trying to) Windows 11 and C3D 2024. Both new-to-me within the last week or so.

I cannot get any apps from the Autodesk app store to show up on my Add-ins ribbon panel. I see only the App Manager  on that panel.

I have .bundle files in a folder C:\Users\<username>\AppData\Roaming\Autodesk\ApplicationPlugins. I have them in several other folders, too, as I find references to folders they might like to be in with Google searches.

I have located the .msi files for the apps that I want and have launched the apps with no warnings. I copied the .msi files around and reinstalled several times. Nothing has worked.

I'm most concerned with getting some apps that I used with Windows 7/C3D2020 to run, and I'm hoping that they are compatible. So to test whether it was just old apps that I maybe can't use anymore, I purchased a (free) app from the appstore. It didn't show up on the Add-ins panel, but it is listed in the App Manager. It's not able to launch from the App Manager, but I can see it there.

I have one overlay (correct terminology?) that I use Sincpac. It is present in the App Manager as well, and is working properly. I uninstalled it as a test and was unable to see my legacy apps or my new one. 

I have some Help tickets in with Autodesk on this, but I'm impatient. I'm here over the weekend needing to produce stuff. TIA, anyone that knows 'bout this.

Autodesk isn't going to help with 3rd party add ins

you need to make sure the apps are compatible with 2024 just because it worked with 2020 doesn't mean it will work with 2024

contact the developers of the add in for compatibility of the version

Some add-ins are compatible, code-wise, with newer releases of C3D. If they use the .bundle format you can try updating the PackageContents.xml file so the SeriesMax value is 24.3 (for C3D 2024).  Example:

<RuntimeRequirements SupportPath="./Contents/Resources" OS="Win32|Win64" Platform="AutoCAD*" SeriesMin="R19.0" SeriesMax="R24.3" />

The add-ins did not all work with 2024.

I'm also new to subscription, and didn't realize I had access to earlier versions until after I posted my question. They loaded up on 2023 using that trick. Thanks @Jeff_M.
