Looks like you have posted twice the same thing. Is'nt it?
And coming to your problem, what error you are encoutnering in doing that?
Also, why do you want to invoke a EXE on the server from a webrequest. You need to exercise more caution to safeguard the server then, particularly when the number of invocations of EXEs increase (though you may check for single instance etc) with increasing number of HttpRequests to the particular web resource.
