I create my installation package but I get the following error when I try and run my software on Client Machine.

ApplicationException
  An error occurred while creating the main form
TargetInvocationException
  Exception has been thrown by the target of an invocation.
FileNotFoundException
  Could not load file or assembly 'ProRodeoChecksLibBO, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

It seems like it can not find the BO Library, but I did copy the entire Subdirectory into the Installation Package. It also shows up on the client machine.

What am I overlooking? I am using a laptop that just has all of the required software to run SQL Express and all of the required .Net stuff.

TIA.
