Installing MPE Cross Compilers ============================== Run the supplied installer executable and follow the on screen instructions. After installation, the manuals are availble from the DOC folder in PDF format. Windows 7/10 and DEP ===================== If you have Windows 7 or another version of Windows with DEP enabled, the compiler may not install. To fix this problem you must turn off DEP (Data Execution Prevention). 1) Goto Windows help, search for "Turn off DEP" and follow the instructions. 2) Reboot - according to several users. 3) Install again. Once the compiler is installed, you will need to leave DEP turned off for VFX Forth and any applications built with it. You can also just leave DEP completely turned off. Because VFX Forth is an interactive incremental compiler, the main memory section is marked as having read, write and execute permissions. DEP causes execution from such a section to fault.
