.Net Excel Add-in Not Loading

[David Robison]

I have an add-in for Excel that typically loads without any problems. On one
of my customer's computers, it refuses to load when logged in as a Regular
User. If he logs in to this computer as an admin, it loads fine. I tested my
add-in using a regular user on my computer, and it loads fine.

What settings should I investigate on his log in to attempt to get my add-in
to load?

The add-in was created using C# in VS 2003. The problem computer is running
Excel 2003 and WinXP SP2.

Thanks,
David

Hello David,

First, please make sure your customer installed the com add-in for all the
users on that machine. If he installed only for the admin, other user could
not use the add-in. He need to uninstalled the add-in and then reinstalled
for all the users.

Second, if he still could not load the add-in, please check the permission
on following register entry

HKEY_CURRENT_USER\Software\Microsoft\Office\Excel\AddIns\

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Excel\Addins\

HKEY_CLASSES_ROOT\CLSID\{5E5E6110-C49E-41FD-891B-7693500F0EC4}]

Then, please also check the permission on the managed Add-in DLL you
develop.

For more detailed information, please refer the following blog article:

I had him uninstall and reinstall the add-in for all users. We checked the
permissions, and he can modify all of the registry entries and files and
folders. I'm not sure what to try or check next.

Hello,

Please ask your customer to check the permission of the registry entry.

Please right click the registry entry and click permission.

Make sure the User account which could not load the add-in have the
permission in the permission dialogbox.

Wei Lu

We got it fixed. My customer logged in as someone else, erased his profile,
then logged back in. It recreated his profile for him and the add-in worked.

Thanks for your help.
