We deployed Excel add-in project which was developed in Office Js in intranet. And manifest file uploaded in Office 365 admin center to reflect users. But it is working in Office online Excel version only. But in desktop version it is not getting refreshing and only showing old changes. Kindly help on this so that it can be upload with new changes to get reflect.
You can remove an add-in that you've previously sideloaded on Windows, Mac, or iOS by clearing the Office cache on your computer.
Additionally, if you make changes to your add-in's manifest (for example, update file names of icons or text of add-in commands), you should clear the Office cache and then re-sideload the add-in using updated manifest. Doing so will allow Office to render the add-in as it's described by the updated manifest.
To remove all sideloaded add-ins from Excel, Word, and PowerPoint, delete the contents of the folder:
%LOCALAPPDATA%\Microsoft\Office\16.0\Wef\
To remove a sideloaded add-in from Outlook, use the steps outlined in Sideload Outlook add-ins for testing to find the add-in in the Custom add-ins section of the dialog box that lists your installed add-ins. Choose the ellipsis (...) for the add-in and then choose Remove to remove that specific add-in. If this add-in removal doesn't work, then delete the contents of the Wef folder as noted previously for Excel, Word, and PowerPoint.
Additionally, to clear the Office cache on Windows 10 when the add-in is running in Microsoft Edge, you can use the Microsoft Edge DevTools.
Read more about that in the Clear the Office cache article.

My team is developing an Office web add-in for Excel built in vanilla Javascript. To test and debug our project, we have been side-loading the add-in as per the usual steps.
Which are:
Navigate to /Users/USERNAME/Library/Containers/com.microsoft.Excel/Data/Documents/wef
Copy and paste manifest.xml file in above directory
Open Excel, click the insert tab, click My Add-Ins dropdown, then select the add-in described by the manifest.xml (which is under Developer Add-Ins)
This process works smoothly for everyone on the team except for one person. For that one person, after they have completed the steps, they see no Developer Add-Ins section, and no options to load the add-in described by the manifest.
What could be causing this issue?

I have an add-in 10 Studio in AppSource.
The current version (on 08/22/2019) is 1.5.1.0. We load well this version in Excel for Windows:
However, when we load the same add-in from the add-in Store in Excel for Mac, it returns the version 1.3.0.0.
It seems that the old version in Excel for Mac cannot be overridden. I followed this method, cleared web cache by using the personality menu from the task pane, and remove everything in ~/Library/Containers/com.microsoft.Excel/Data/Library/Caches/. But the old version was still there and could not be overridden by the new version from the Store.
Does anyone know what's happening here?
Did you try first removing the old version?
How to uninstall an Add-in (Mac)
If you wish to uninstall an Add-in completely, delete, move or rename the original Add-in file.
When ticking or unticking the Add-in, a message box will appear, asking for permission to delete the reference to the Add-in. Click Yes.
The Add-in will no longer appear in the list of Add-ins.

We created a simple PowerPoint content add-in. As the documentation says, content add-ins should work in the Office 2013 and newer:
Content add-ins are supported in Excel and PowerPoint in Office 2013 version and later. If you open an add-in in a version of Office that doesn’t support Office web add-ins, the add-in will be displayed as an image.
It works as expected for most of our clients but for some of them it doesn't work in a strange way:
when PowerPoint is in the edit mode, all is ok, the content add-in is rendered and it is interactive
after PowerPoint is switched to the present mode, only a non-interactive screenshot/image of that content (previously displayed in the edit mode) is rendered and users are not able to make any interaction
Even the official Microsoft Web Viewer content add-in on that particular computer doesn't work - all web pages are displayed as screenshots in the present mode.
Any ideas why it works fine on most of the computers and on some doesn't?
SW versions installed on that "problematic" computer:
PowerPoint 2013 (15.0.5093.100)
Windows: Windows 10 Home (1803, build 17134.523)
Internet Explorer 11: 11.523.17134.0
Do you know if this is possible to create a VSTO add-in for excel in an office 365 suite (on desktop, of course)?
Officially, it says it is supported.
But, if I create an empty project on VisualStudio with the default "Office 2013 & 2016 VSTO add-in", it does not load.
But, it works on other machines, with excel 2016.
Can you help me with this?
I already tried many things. And, it seems that the add-in does not even show in the list of COM add-ins in the setup menu. It's not disabled; and, if I look at the registry, the load behavior is 3.
The only strange thing that I found is that when I try to link manually the .dll file using the "add-in" menu, it says that the dll is not a valid excel add-in.
But, if I do it another way and click to the .vsto file, the explorer says that the add-in has been installed correctly..
Thanks a lot
I have an application that is developed using CommanBar tools. As there are much constraints in that, i have planned to shift to the Ribbon(view designer). I created a project like, File->New Project->Excel 2007->Excel Addin for 2010.
Created a sample addin and added a new project to the same solution as I wanted the addin to be added using installer(.msi). I registered the Com Addin in the Registry, but on uninstallation, the files are getting removed only in the registry entry, but not in the MS Excel, the addin still to be remained there. Please help me in this. As I am new to the implementation of Ribbon implementation.
I have used winform c# 4.0.
Thanks in advance.
#kiru - the screen shot for the path you mentioned
Check the path from where the addins are been loaded.
Open Excel
Click File => Options => Addins (Tab)
Select COM Add-ins in Manage dropdown box and click Go
Select the addin and you can see the path where it is been loaded.
If it is from bin directory then follow this
If you are running your msi on development pc clean your solution every time you test your msi.
