[version 4.3.3] Short explanation how to create/install the 4nec2 environment
		(Windows-95/98/ME/NT/2000/XP)

1) Create 4nec2 main directory (normally C:\4nec2)

2) Unzip 4nec2 files by double clicking 4NEC2vXXX.zip

3) Extract all files into the 4nec2 main (home) directory

  -->	NOTE: BE SURE YOU SELECTED THE 'use folder names' OPTION !  <-- 

	This option will create the '\exe', '\out' and '\pov' directories in your 
	4nec2 main directory. Afterwards all the required files are automatically
	copies onto the corresponding directories.

	If these directories were not created, do so now manually and move all 
	files except the '*.nec' and '*.txt' files to the '\exe' directory.

	(For windows-me you simply may select all the files in the compresses
	folder and drag them to the newly created 4nec directory)

4) If required (see note a), unzip additional (system)files by double clicking 
   4NEC2sup.zip and place these files into 4nec2\exe directory.

5) Create shortcut for 4nec2.exe (view.exe, build.exe) and copy shortcut to desktop

	- select file '4nec2.exe' in '\exe' directory
	- click right mouse button
	- select 'create shortcut'
	- drag 'shortcut to 4nec2.exe' to desktop

5) Read the below notes before trying to run the program.

*****************************************************************************************

Note:	a) 4.0 and later versions use some general system files which on most modern com-
	   puters already will be available. To avoid download time, and to be able to
	   distribute the package on floppy-disks, these system files are placed in a 
	   second supporting zip-file, called 4nec2sup.zip. If one or more of these files
	   do not exist on your computer an error message containing the name of the 
	   missing file is generated. The following system-files are used:

	   				- msvbvm60.dll		(1352 Kb)
					- msflxgrd.ocx		(239  Kb)

	   If the msvbvm60.dll file is not included in the package, you can to download
	   it freely from the internet. There are a number of sites who will deliver this 
	   file for you.

	   These system-files have to be placed in the following directory:
		- Windows 95,98,ME : 	C:\Windows\System
		- Windows NT : 		C:\Winnt\System32
	   To register these files, go to the start menu, click Run and enter:
		- Windows 95,98,ME :	REGSVR32.EXE C:\Windows\System\<systemfile>
		- Windows NT :		REGSVR32.EXE C:\Winnt\system32\<systemfile>
 		Enter the appropriate filename for <system-file>
 
	b) The nec-2 calculations for the 4nec2 program are handled by so called nec-2
	   engines. There are two different types of engines available: 1) the original
	   nec2d engine by Jos Bergevoet, and 2) the nec2dXS engine. Both engines have
	   their (dis)advantages. 

	   There are different nec2d(xs)***.exe's available for increasing number of 
	   segments. The required executable is automatically selected by 4nec2 according
	   the number of segments set in the 'settings' menu on the 'main' form.
	   
	   The 'biggest' executable that can be used on your computer depends on the amount
	   of RAM memory available on your computer. If RAM is not enough a "not enough 
	   memory-error" is generated, and you will have to decrease the nr of segments. 
	   Note however, that when (according the 4nec2 help) a certain executable should
	   just run, but there is too much memory in use by Windows, more obscure errors 
	   like "Error opening input file" could be generated.

	   For the original nec2d engine, the 'smallest' exe that can be used also seems
	   related to the amount of  RAM. When using a 'simple' nec input file with few 
	   segments in combination with a 'small' exe, but with a big amount of RAM, a 
	   message "Program requires MS-DOS mode,...." might be displayed. If this is the
	   case, increase the number of segments, till the message no longer appears.
	   On the other hand, don't set a far too big number of segments, because this
	   will decrease calculating performance.

	   Nec2d (dis)advantages:

	   + Faster when using the Optimizer/Evaluator.
	   + For 'small' exe's faster than for 'big' ones (same nr-seg)
	   + Especially suited for the 'older' windows-95/98/NT systems.
	   - Reduced precision when using SomNec ground inside frequency loop.
	   - Does not run on Windows-XP

	   Nec2dX (dis)advantages:

	   + Runs on all Windows systems
	   + Maximum precision when using SomNec ground with frequency loop.
	   + No separate executable required for SomNec ground calculations.
	   - Due to start-up time, slow when using Optimizer/Evaluator.
	   
	   When using the original nec2d engine and your actual number of segments is 
	   just above the maximum you could run on your system, selection of the new
	   nec2dX engine could sometimes solve your 'problem'
	   (Use the settings option on the Main window to change between engines)

	   Nec2d executables for 256 and 512 and Nec2dXS exe's for 500 and 1500 segments
	   are included in the 4nec2 package. Executables for more segments can be found
	   at the nec-2 homepage on  "www.qsl.net/wb6tpu/swindex.html"

	c) When using none-default desktop (color) settings, it is possible that one or
	   more windows are not correctly painted. When using a none-default setting,
	   please temprary switch back to the default desktop (color) settings to check
	   if, for both settings, the same information is visible.

	d) See 4nec2.hlp for more information about 4nec2 functionality. 4nec2 help in 
	   printable form is included in the file 4nec2.rtf. You can print this file for
	   comfortable reading. Also the file _GetStarted.txt might help you find your
	   way through the 4nec2 package.
	
	e) The Nec-2 user manual can be found at "www.nec2.org". Select the word document 
	   and place this file as 'NEC2.DOC' in '\EXE' directory for viewing with F10 key.

	f) When you try to read-in an incomplete *.out output file (caused by nec2d errors
	   or because calculation was not yet finished), it is possible that a 4NEC2 program 
	   error is generated because of the incomplete data. To solve the problem, Remove 
	   the '*.out' file from the '\OUT' directory and try again.

	g) Due to the DOS nature of the original somnec2d program, the maximum file-name
	   length for *.gnd files is restricted to 8 characters. When you run a lot of dif-
	   ferent (high)freq/cond/diel settings, it is occasionally possible you get an 
	   "Error on groundfile" message. It this is the case, remove all *.gnd files 
	   and try again.

	h) When no *.out output is generated by the nec-2 engine (check the \out folder), 
	   please set the "Wait for DOS-box option" in 'Settings->General settings' on the
	   "Main" form, to see what error message is logged. 
	   Furthermore you could temporary remove the "@echo off" line in the 4nec2.bat 
	   file in the \exe folder, by adding the characters "rem" before it. This should 
	   deliver even more logging.

	i) If an "out of environment space" error is generated, please read the 
	   '_Out_of_env_space.txt' file included in the package

	j) When key's F6, F8 and/or F9  won't work you probably have a different path to 
	   the notepad, wordpad or word text editor's. You may customize this by changing
	   the MS-DOS directory path specified in 4NEC2.INI.  You can locate your notepad,
	   wordpad or word text editor executables; NOTEPAD.EXE, WORDPAD.EXE or WINWORD.EXE
	   with: start-> find -> files or folders.

	k) If you enjoy this software, you could send me a note, so that I can inform you 
	   when new versions are available.

	l) If you should experience any problems installing and/or running the 4nec2 program,
	   or for suggestions, questions or remarks, please contact me at:
