"Application requires that assembly *** be installed" error while trying to install my ClickOnce app

Here's an error I get when I try to install my application from the publish location:

I have my application (and a DLL used by it) linked to version 1.61.4111... of QWhale.Common which is a 3r开发者_Go百科d party DLL. I have been used this version since about 4 updates ago and never had this problem. I have no idea which part of my application or DLL could be trying to link to the older version. The only thing I did different on this version is that I moved my application's project folders to a new location in my computer.

Where should I start trying to find where this problem is coming from? Did you ever have this problem before?

As Yahia commented, this can be a licensing issue but if you've been using this assembly for a while and if you've been compiling it with your application, there is a chance that a setting associated with the file could have changed with your projects settings.

Assuming you are using Visual Studio, I recommend opening your Projects properties window and navigating to the Publish tab and opening the Application Files Dialog.

From there, find the referenced, 3rd party assemblies make try setting the Publish Status to Include and the DownloadGroup to (Required).

Save your changes and republish your application.
