Experts?

Is the right version of the .Net Framework installed on the client machine?
Are you using references to some OS Dll's that might be or not included on different versions of windows?
Are the machines using the same service pack for the OS, same service pack for the .Net Framework targeted application?

In a nutshell, would you please provide some information on the configuration of the machines where your setup works and where it doesn't?
