COM Object that has been separated from its underlying RCW cannot be used

Hi

Anyone know what this error is? Never had it last week but it appears now since I ran an update.... Ive tried turning just about everything off but I still get it when I close inventor. It is related to my addin I am working on because when I unload it, I don't get the error.

Here is the error

Here are my references

Any help greatly appreciated, I really don't want to have to start from scratch 🙂

Thanks

Hi Martin

Weird. I too unloaded the interactive Tutorial and now i do not get the error. That is strange because i dont have anything in my application that would require the interactive tutorial. Would like to establish exactly what the error is because i cant make an addin that requires this to be switched off, especially when other addins don't experience the same issue...

@Anonymous

Have you ever seen this before?

Hi Nacho,

it seems to be that this error was new up to inventor 2017. In 2016 it doesn't happened.

I solved it temporarily by deleting this lines in the addin server class:

 'If AddinGlobal.InventorApp IsNot Nothing Then
   'Marshal.FinalReleaseComObject(AddinGlobal.InventorApp)
 'End If

Now, Autodesk should have a look at the interactive tutorial dll.
