missing third party updater

[BJX916_XUANWU115]

Hi everyone.

I am using Revit 2025, I closed the model yesterday and uploaded the model to Autodesk viewer.  When I reopened the model, a warning popped up:

I did some research and found this from Autodesk:

https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/Error-Missing-Thir... 

But the problem is I didn't use any plug-in when I created this model, and this is not a central model, all I did just uploaded it to Autodesk viewer, then why did I get this problem? And which solution should I take that won't affect my model? When I opened another model, I didn't get this warning.

Anyone has got this issue? Any help would be appreciated. Thanks.

Was the Autodesk Viewer link shared with anyone else? I can only think it has been opened on a PC with an addin?

Can you review what addins you do have - Manage Tab > Extensions Panel > Add-Ins Manager

[BJX916_XUANWU115]

yes, the model was shared to someone via a link. I did install add-ins on Revit 2025, but I didn't use any of them when I created the model.

I didn't see the extension panel, but I have add-ins tab:

Choose option 2.

do you mean to choose "Do not warn about this updater..." or option 2 from the link: Install the 3rd-party add-on?

The Add-ins are also the additional Tabs such as DiRoots Mlabs plus the Coins addin so these would be party to the issue!

The Add-ins are also the additional Tabs such as DiRoots Mlabs plus the Coins addin so these would potentially call the message!

Yes it is quite obvious unless you are reading from bottom up.

I see, thank you for your help.
