c# setup generates error when I want to publish the program

Hello,
 The soltion works correctly on my machine...
On a server, in the past I have copied .exe and .dll files, etc in the C:\program files folder of the server. The clients then just run the .exe from the server and all works fine...
Now I would like to create a setup.exe for each client...
 I have published the .exe and it's relevant .dlls onto a test server.
 On the client machine, I point to the test server to run the setup.exe
 At the end of the setup on the client, an error is given and when I trace the file to see the error, it has
 the following in it.

So the issue is that the setup program generates an error.
The client runs the setup.exe and right at the end it gives an error.
But can not find out what it is that is causing the error.

Do you know what is causing this error please?
 The only CLR related .dll I found on the application files which I added was "Microsoft.SqlServer.SqlClrProvider.dll"
