SHC> system("XCOPY", "KCPSM3.EXE", $s_tempLocation, "/R", "/Y");
it helps to explain why that should work. if you pass a list of values
to system or exec, it will bypass the shell or perl splitting the string
on spaces. that means the last arg would have been '/R /Y/' which is not
a valid option in winblows. by splitting it up into two option values,
that should fix it. another solution would have been to call system with
one string and then perl (or the shell if shell metachars are found)
would split that on white space and usually do the right thing.
this is all documented in perldoc -f system so the OP should read that
and learn more about how to correctly use system.
