Lack of Office 365 (local instal) COM Automation support - need a definitive list of the versions and their support for automation.

Question

I develop an application that does some PowerPoint automation using embedded interop types (C# App - with VB assembly that does the office automation part)
I've started to get reports that the PowerPoint automation is failing on Office 365.
Here is a sample of a typical customer complaint:
not exporting to powerpoint...
We recently migrated from Office2007 to O365. That would be definitely the reason.
But how can we solve this?
I found the following reply to a forum question:
https://social.msdn.microsoft.com/Forums/office/en-US/3c95eea4-641f-4bf0-a166-ecf33177854b/does-desktop-versions-of-applications-in-office-365-packages-support-comautomation?forum=exceldev
But it only states that one version doesn't - and then one version does - doesn't reference a list of all support versions.
Also - later - in that thread - it is shown that the accepted answer is actually incorrect.
A sample of the type of code used to interact is shown here....
    Public Function PositionSlideTitle(ByVal slide As PowerPoint.Slide, ByVal height As Single, ByVal marginX As Single, ByVal marginY As Single) As PowerPoint.Shape
        Dim shapes As PowerPoint.Shapes
        Dim shape As PowerPoint.Shape
        ' get the shapes on the slide
        shapes = slide.Shapes
        ' get the shape that holds the title
        ' if the shapes collection has a title, then this title shape is always in index 1
        If shapes.HasTitle = Office.MsoTriState.msoTrue Then
            ' the title shape can also be accessed by the special property Title
            shape = shapes.Title
        Else
            ' If there was no title - then add one
            shape = shapes.AddTitle()
        End If
        ' position the shape at 0,0 (seems not to want to go there)
        shape.Left = marginX
        shape.Top = marginY
        ' stretch image to fit slide
        shape.Width = slide.Master.Width - (marginX * 2)
        shape.Height = height
        Return shape
    End Function
The project references Microsoft.Office.Interop.PowerPoint, version 11.0.0.0 with it's "Embed Interop Types" set to true.
This has worked for 10+ years, with all versions of office from Office 2003.  We still need the application to support Office 2003 - and it still does perfectly, so referencing newer PIA's isn't an option.
Please help.

Great to know that all versions of Office Support Com Automation.
Because the end-users that have made the complaint - are using Office 365 - it wouldn't be the Click2Run edition as you've mentioned - but it's good to know that information, as I wasn't aware there was a possible issue with that - thanks.
I'll just assume then that the end user that sent the following issue is running them with different permission level:

Although - one more thought - I read somewhere that O365 users can install office via the O365 portal - I wonder whether this is the same as Click2Run install - and hence causing the same out-of-process application error you have referred to?
Kind Regards
UPDATE:
Further reading/searching on click-to-run and O365 found the following:

Eugene - you may be onto something with the click-to-run issue - that may be the cause of the error in O365 installations - At least now I have a scenario to test against (user info is always difficult to determine exactly how to replicate issues) - Cheers.
