@saiparth there is little we can do to troubleshoot the problem without seeing your code.

Code to execute AutoIt

case "fileName":
                        process = Process.Start(@"E:\graderDocs\graderWord_0_score\word0.exe");
                        break;

AutoIT script

WinWaitActive("Open")
Send("C:\graderDocs\graderExcel_22.5_score\Last_First_sk16_xl_ch1-4_grader_cap_hw.xlsx")
Send("{ENTER}")

Its working fine in my machine & Friends machine.Only while executing in selenium grid its failing.

Thanks,
