Item talk:Q131920
This software came with the option to install Visual C++ 2.0 (32-bit) or Visual C++ 1.51 (16-bit). I was only able to install the latter. One other thing to note: CodeViewer for Windows and CodeViewer for MS-DOS are both installed, but only the latter opens.
The NSRL photos didn't include any system requirement information, and neither did the ReadMe file. I found an external source, which suggested that Windows NT 3.5 was the one compatible OS for this software. There's a note that says "this product will not run under Windows 3.1 or WFWG. This product will run under Windows 95." Unfortunately, I found the metadata after doing the install and didn't install on Windows 95. I managed to install on WFWG 3.11 and it seems to work fine--who knows!
Additional requirements: IBM compatible 386 (486 recommended) processor; VGA monitor 640x480 (SVGA 800x600 recommended); 16 MB RAM (20 recommended).
