For checking framework problem I made one simple application in which i am trying to read config file values on button click as MessageBox.Show(ConfigurationManager.AppSettings["FlagForArchiving"].ToString()); but i am getting error as 

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Please help me to solve my problem.Thanks in advance.

FileNotFoundException means that the config file is not present in your app folder. Make sure the config file is deployed when you publish the application.

Yes, you need to have a config file on each machine where your app is installed.

Change the profile to ".NET Framework 3.5". The ".NET Framework 3.5 Client Profile" has a couple of limitations and will not offer all assemblies you might need.

Probably because of directory accesses. Run your application via administrator to guarantee access.
