Outlook Add-In loads but is not showing - outlook

Question

My solution consists of 2 add-ins: 1 for Outlook and one for Word. They load and work perfectly in Debug mode. Both based on Add-In Express library. Both are registered correctly during install, for example: adxregistrator.exe /install=MyOutlookAddIn.dll /privileges=admin
The installer works fine and everything completes successfully. When I open Outlook I can see the MyOutlookAddIn is in the list of Active Add-Ins. However, my custom Ribbon Tab is not showing at all.
When I run Fusion Log Viewer I see the following message. It is very strange because I do not have any assemblies with the name MyOutlookAddIn.resources.DLL and none either generated automatically...I googled all day long but at no avail. I can't find any reason for these error messages (assuming that the problem come out from it). Any clues of pointers are greatly appreciated.

=============================
Apparently I resolved the error messages in the Fusion Log by using solution proposed here:
AppDomain.CurrentDomain.AssemblyResolve asking for a <AppName>.resources assembly?
However it did not resolve my main problem that my Outlook Add-In does not show in Outlook despite that it is shown as loaded...Any other tools I can use to find where the problem is?

Answer 1

I suppose the installer doesn't include the Localized Resources project output. And check if there're problem in the adxloader.log file.

Answer 2

What version of Add-in Express do you use? Please check if the 'Show add-in user interface errors' option is enabled in Outlook. If not, try to enable it and restart Outlook. Probably you will get any ribbon UI errors. You can also send a sample project to the support e-mail. I will test it on my PC.
