help with design

Hi,
I need to create a few classes that I can reuse in my applications and also
distribute to other programmers on the team. After creating the classes I
want to put them in a package and distribute them .When the distributed
package is run it will install my .dll in the GAC so that all we have to do
is to reference imports mydll. How do I create this. I tried creating a class
library, assign a namespace for all the classes, then compile, then giving it
a strong name, after creating the keys I edited the assemblyinfo.vb file and
added
<Assembly: AssemblyKeyFile("..\\..\\company.keys")>

Error creating assembly manifest: Error reading key file
'..\\..\\company.keys' -- The system cannot find the file specified.

This file is in the root dir of my app.

Also if I edit one of the classes in the future, do I need to remove it from
the GAC and then reapply it? How do I deploy the updated dll to the other
users?

Thanks
I get the error when I compile
