Launch exe file from network location using dynamics CRM plugin - plugins

Question

I am trying to launch .exe file from network location in dynamics crm plugin using code snippet
if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
{
Entity account = (Entity)context.InputParameters["Target"];
if (account.LogicalName == "account")
{
Process.Start(#"<NetworkLocation>\abcTest.exe");
}
}
And the snippet throws exception. Any idea how can I launch that .exe from network location.

Update 1
It is Dynamics CRM on-premise environment and the file is not on the CRM server.
Update 2
Both exe file and CRM are in the same network.
