Easy Code (http://www.easycode.cat/English/) is actively developed, has dual versions for MS Macro Assembler (Masm) and Jeremy Gordon's Go Tools (GoAsm), and comes in a zip, ready to be run portably -- it saves settings to 'EasyCode.ini' inside the program folder, but you need to run the included 'Settings.exe' prior to the first run and de-select all options.
The included help file also states "Easy Code includes the '/C' (or '/c') switch in its command line for using configuration files other than the default one ".

The Easy Code interface, looking like Visual Basic, allows you to program Windows assembler applications (executable files, dynamic and static libraries, COFF object files, console applications and drivers) done in an easy way as was never possible before. Download and test this application including the source code of a nice CD player, a complete and fast text editor in a dll file (to be able to program your own editor), a complete and excellent text editor ready to use, a file shredder, a MIDI player and many other applications.
