Hello Lads,
I've just upgraded to VS 2015 and I'm getting get a COM exception when I load an existing Add-In Express project.
Here's the sequence of events:
1. Uninstalled Add-In Express
2. Uninstalled VS 2102
3. Installed VS 2015
4. Installed Add-In Express v8.2.4371
5. Opened existing Add-In Express project
6. Open an existing (Word) Advanced Task Pane and voila the following exception:
Error HRESULT E_FAIL has been returned from a call to a COM component.
(Call Stack is at the end of this post)
The pane is blank (all the controls have disappeared)
Other observations:
- there are no missing/broken references
- All other Project properties "look" as expected
- "Make Assembly COM-Visible" is checked
- If I add a new ADXWordTaskPane1 there is no exception
- Ironically enough the project compiles
I suspect I'm missing something fundamental but I haven't been able to identify it.
Any thoughts?
Cheers - Marcus

Hello Marcus,
Can it be that you haven't installed some components that your project uses?
Also, make sure that Add-in Express references don't specify a specific Add-in Express version (which isn't installed on your machine). Then rebuild the project and check compile-time errors.

Hello Andrei,
I've solved this issue and thought I'd share the outcome for others who may experience similar symptoms.
To re-iterate, I simply uninstalled VS2012 and Add-In Express, then installed VS2015 and the same version of Add-In express I had uninstalled. There were no other 3rd party components involved.
The ADX add-in - which worked that same morning under VS2012 - now resulted in the following error upon opening:
"Error HRESULT E_FAIL has been returned from a call to a COM component"
You wouldn't believe how many different variations of this error I found - each with a different resolution.
In this instance the solution was ridiculously simple.
Somewhere along the way, my project had a reference to itself!
I checked the proj file from a back-up. This self-reference was already there under VS2012.
I don't know how it happened, but while it was not an issue for VS2012, it was a problem for VS2015.
So if you upgrade to VS2015 and find the error above and your forms or Add-In Express panes are all blank with no controls visible, check your references to see if there is a reference to your project's own DLL. If there is, simply delete it.
(I'm still scratching my head how it happened!)
Andrei, please accept my sincere apologies for even *thinking* it could have been a issue with ADX :)
All the best, Marcus |
