This is version 16.51 of Fractint for Windows. Fractint for Windows requires Microsoft Windows version 3.0 running in either Standard or 386-Enhanced mode (the program is flat out too big to run in "Real Mode"). This file is only here to ease your mind a bit ("what, no DOC file?"). Other than this file, the only documentation is in the on-line Help screens. By now, you have discovered that the ZIP file consists of WINFRACT.EXE, WINFRACT.HLP, and a few FRM, MAP, IFS and L files. WINFRACT.EXE and WINFRACT.HLP are required to run the program and obtain online Help (and you *will* need to look at the on-line help, as it's the only documentation you are ever gonna see for this release), and should be copied to the same directory. The FRM, MAP, and IFS files are direct copies of files in version 16.0 of Fractint-for-DOS and are only required for specific fractal types (if you already *have* version 16.11 of FFD, you can use its copies of these files instead). Just unZIP these files into some convenient directory, and either call the program manually using the File Manager or the "File Run" option of the program manager, or install it permanently using the "File New" option of the Program Manager. Enjoy.
