201. c# deployment -- Exception Info: System.IO.FileNotFoundException    at lab651_ptt.PTTService..cctor()

We have a successful build we are happy with in C#.
We are trying to run the executable on another windows machine.

The exception is below.

Any ideas?

Dear Mike,
Please check the sample project(HelloPTT).
Is it working?
"FileNotFoundException"
I guess the file could mean DLL files.
Please check it also.
Regards.

HelloPTT, without modifications, results in the same exception.
(It can't deploy either) 

The programs will run on a machine with Visual Studio installed, but they won't run on a machine without it.

Description: The process was terminated due to an unhandled exception.
Exception Info: System.IO.FileNotFoundException
   at lab651_ptt.PTTService..cctor()

Exception Info: System.TypeInitializationException
   at lab651_ptt.PTTService.getInstance()

It is almost like PTTService.getInstance() is opening a file. 

It is possible it is a setting in my system...
Any thoughts?

We have tried the Linux API, SIP, even experimented a bit with Android to get our application to work. We have a successful application with C#,  but we can't demo it on anything with visual studio installed.  Thank you for your help.

To deploy, you need to check the dependuncy files by depends.exe(Mocrosoft tool).
I think you need to install Microsoft Visual C++ 2005 Redistribution.
