Updater giving a warning message before the Revit document opens

[IbrahimNaeem]

Hello,

I have created an addin which use an updater, the updater works fine but have two errors:

1- First Error, when I reopen a project where I used the updater in before it's giving me a warning message that the updater used before doesn't exist. Any ideas of how to get rid of this message because the updater is there and loaded with the Revit start-up normally and works fine after I neglect this message? 

2- Second Error, Sometimes it stop working but when I stop it and activate it back(have two buttons to activate it and stop it), it works fine. Any clarification why it's having this strange behavior? 

Thanks, Ibrahim Naeem

Hi @IbrahimNaeem,

Have you used the 'isOptional' overload of RegisterUpdater?: http://www.revitapidocs.com/2017/b83ef3b6-e567-97ae-c33c-181b281b3287.htm

Are you unregistering/reregistering the iupdater, or just adding/removing the triggers when using your activate/stop buttons?

Are you registering the iupdater per document, or at the application level?

I'd need to see some code to comment further.

Cheers,

-Matt
