Change add-in load order

TA.Fehr — Thu, 05 Sep 2024 13:40:06 GMT

I have an add-in that utilizes references to Vault. However, I've found that in 2025 if my add-in loads first, the vault add-in fails to load. I've changed the ClassID of my add-in to load later with no effect, and tried using the suggestions found here, here, and here.

The issues is that the only way I can place a wait on my add-in is at the ApplicationAddInServer.Activate stage. Which means that my add-in is already activated preventing Vault from activating. I tried programmatically deactivating mine and activating vault, but this causes an unknown error when I activate the vault add-in. The only way it seems is to start Inventor with my add-in set to not load automatically and then manually load it once Inventor starts, which I naturally wish to avoid.

Vault addin is loaded when start up. In IV2023.

If your addin load on files open (part), it should work.

Unless you need it to load on start also.

Don't if your addin can loop and wait and check of Vault addin is loaded.

Thanks for the quick reply.

This reference states that the add-ins for Inventor Pro only load at startup and not in session. So I can unload it later, but since it has already been loaded when Vault add-in wishes to load, vault never loads in order to activate it later.

This matches what I've been seeing, where I can have the buttons load in assemblies/parts/drawings etc, but the add-in itself loads only at startup.

My addins are not loaded in Startup (since at least IV2012), Vault is:

LoadBehavior is set in the .addin file.

Right, I had long since set that and forgot about it. I have mine set to

I'll fiddle around with this and see if I can get different results.

Thanks for the pointer.

I tried this in iLogic:

Dim oAppAddin As ApplicationAddIn Dim oAppAddins As ApplicationAddIns oAppAddins = ThisApplication.ApplicationAddIns For Each oAppAddin In oAppAddins Logger.Info(oAppAddin.DisplayName) Logger.Info(oAppAddin.Activated.ToString) Next

Should be able to do in addin and check if Vault is loaded/active.

Question is: are addin loads in parallel?

If not, waiting for Vault to be active will not work.

@Frederick_Law , you were correct to reference the load behavior setting.
My .addin file was still built on an older template so it referenced <LoadOnStartup> and not <LoadBehavior>

Replacing <LoadOnStartup>1</LoadOnStartup> in the .addin file with <LoadBehavior>1</LoadBehavior> resolved the issue.

Thanks

The way you describe the addins not loading - sounds like it could be a dependency issue. Your addin and the vault addin may be trying to load different versions of a dependency and that is causing one of them to not load afterwards.
