Referenced Assembly is not copied when I export the project

[djurio]

I am referencing the assembly System.Data.SqlServerCe.dll in order to query a table in a sqlserver ce database.
When I launch the program in my computer it runs correctly but when I put it in the terminal ask for the System.Data.SqlServerCe.dll assembly. I've seen that this assembly is not copied to the output directory once I build the project.
I don't know why it's not copied because other assembly that I've referenced it's copied.
The only diffence is that I did the last library.
I hope someone could help me with this problem.
Thanks!

I've already solved it. The problem was that I was using an older version of sql server ce. Adding the same version I could download the project.

Thanks
