Hello Andrei,

A client let us know that in our addin express word addin plugin the taskpane was not showing anymore. I tested in my own word and indeed it is not showing again. I checked the code in debugger and it seems the taskpane is not autocreated anymore and WordTaskPanesManager.items[0].CurrentTaskPaneInstance is returning nil.

I guess microsoft has once more changed something to internal window stuff related to taskbars and it has broken taskbars again in addin express plugins.

My word version is currently this :

when i downgrade to Version 2501 (Build 18429.20132) taskpanes work again. 


cd %programfiles%\Common Files\Microsoft Shared\ClickToRun
officec2rclient.exe /update user updatetoversion=16.0.18429.20132


i had also tried version 16.0.18429.20158 but taskpanes did not work again there

Hmm,

I do not understand i upgraded to 2502 again and taskpanes still work. Do you guys or microsoft have a way to control some settings / features remotely ? like to enable or disable certain functionality was it certainly did not seem to be tied to a specific version and it started working again all of a sudden

edit: no it does not work, on 2502 but somehow if you immediatly restart it after upgrading again it still worked but needed an extra restart of word after upgrading again and then it started failing again

so it definatly does not seem to work 2502 version

No. Add-in Express panes rely on the windowing of Word and it looks like they change it.

Hello Tim,

Hello Andrei,

Thanks but the instructions seem to be related to the dot net version of addin express while we are using the vcl version so i have no clue how to proceed with that. We also build against the source code of addin express vcl so not sure what we can do with the 2 dll's. Is it possible you may have mixed instructions for the vcl version with the instructions for the person in the dot net forums having the same issue ?
