Check Text ( C-29906r1_chk )
Using Windows Explorer, search the system for the existence of known compilers such as msc.exe, msvc.exe, Python.exe, javac.exe, Lcc-win32.exe, or equivalent. Look in all hard drives. Also, query the SA and the Web Manager to determine if a compiler is present on the server. NOTE: This check does not prohibit the use of the .Net Framework or the Java compiler for Oracle. NOTE: ColdFusion would not be considered a compiler as long as the site is not using the tool for development work. Any compilers required to be present on the systems need to be restricted to administrative users only.
