Hi,

I have an add-in that I have deployed through clickonce repeatedly with succes.
Now I have a user where the installation goes correctly (no errors), the add-in shows in 'add/ remove programs'.
But it does not show up in Excel. It does not load, it does not show up in Add-ins (not as loaded or disabled).

I checked the Excel setting, it should accept add-ins without trusted computing.
No error messages in Excel, it's just like it's not installed at all.

I targeted .Net Framework 4.8 which is installed on the computer (by default in Windows nowadays).

Do you have anyhting else I could check for?

Hello,

Install the add-in on your machine, use section Locating COM Add-ins in the Registry (see the PDF file in the folder {Add-in Express}\Docs on your development PC) to find the keys created fro your add-in and check if these keys exist on that machine.

This is that key in his registry.
The only one that looks different from mine is the ADXStartMode, mine says NORMAL.

Hello,

That section lists these keys:
- add-in key
- ProgID key
- CLSID key

You've found the add-in key. The other keys play the COM role of your COM add-in.

I'm looking around in my registry (where it works) but can't find the keys you're saying..
What would be the path?

In that section, there's a screenshot showing how the Guid and ProgId attributes defined in your add-in module are mapped to the three key types; note that your registry may contain each key type several times: you see them when you search the registry using regedit.exe. This occurs because the registry contains separate branches available for 32bit and 64bit programs.

Do you have a registry path where I should look?

No. The actual path is constructed using the Guid and ProgID attributes. You could search the Guid value and the ProgId value in the registry.

Ok I got this key:
Computer\HKEY_CURRENT_USER\Software\Classes\CLSID\{9E19EBCF-6858-4052-9D09-6910304AFB36}

And it stores this on my machine:
https://xlconnect-my.sharepoint.com/:i:/g/personal/gjvdkamp_xlconnect_net/EdGu-EVAcktIudxxzlAYowoB4XUO5jtB4hu649x1yPutvg?e=TBpvsY

I should get that for the machine that doesn;t work?

Yes. I would search that guid both on your machine and on the affected machine.
