MSWindows version of NEURON
Binaries only. (NEURON sources are identical to those in ../unix/nrn3.2.tar.Z)
Able to compile and dynamically link membrane mechanisms.

0) Requirements: 386 or above running Windows 3.1. At least 8MB of
RAM. NEURON won't work with 4MB ram. 10MB disk space. (20MB if you install
the portion that compiles membrane mechanisms and creates dll's)
If you compile dll's, gcc is pretty slow with 8MB RAM due to swapping.

If you already have
win32s or are using Win95 or NT
don't bother with pw1118.exe and go to step 2.

1)
Install win32s by executing the self extracting pw1118.exe archive
in an empty temporary directory and following the readme.txt instructions
extracted from that file. After installation of win32s you may delete the
temporary directory.

2)
Copy nrndisk1.exe and nrndisk2.zip to an empty temporary directory and
move to it.
DO NOT UNZIP any files, the installer will do that for you.
If you manually extract neuron.exe from nrndisk2.zip you WILL NOT be able to
run it unless you know what you are doing since it looks for
several other files and environment variables.
If you download nrndisk2.zip under win95, make sure that is the DOS name
of the file. If not, go to a dos box and rename it to nrndisk2.zip.

3)
Execute nrndisk1.exe in this temporary directory.
(nrndisk1.exe is a self extracting archive that contains the install program
for neuron.)

4)
Execute the install.exe program in this temporary directory
and follow the instructions.
After installation you may remove the temporary directory.

4a) The installed version of nrn/lib/hoc/funfit.hoc is out of date
and should be replaced by the
ftp://ftp.neuron.yale.edu/neuron/mswin/funfit.hoc file.
5)
Look at the Notes file in the %NEURONHOME% directory.

-------------

It is not necessary to uninstall before installing a new version of
neuron. However to uninstall, do the following:
1) remove the directory created by the install program where the
neuron software resides. This will free a good deal of disk space.
2) remove the neuron program group
3) optional: edit the win.ini file and remove the [INTERVIEWS]
and [NEURON] sections.
4) optional: edit the autoexec.bat file and remove the NEURONHOME and
DJGENV environment variables. And eliminate the neuron path directory
from the PATH.
5) optional: remove (or return to its original state)
the shell command in config.sys. (The neuron installation may have
increased the environment size to 5000.)

Problems running neuron.exe?
-----------------------
Is NEURONHOME set in the dos environment? Is %NEURONHOME%\bin in your PATH?
NEURON can now run without NEURONHOME or modifications to the win.ini
file but it is still best to have at least the NEURONHOME environment
variable.

Check the properties of the NEURON Demo icon. Did the working directory
get set. (We have had some problems with some program managers not
setting the working directory). For the demo the working directory has to
be %NEURONHOME%\demo.
If things still don't work read the Install.txt file.


User Defined Membrane Mechanisms
--------------------------------
If you wish to write your own membrane mechanisms using the model
description language, they can be compiled into a dll and dynamically
loaded into neuron.exe. You do not need to install the mknrndll part if you
already have a dll file containing the desired mechanisms. The mknrndll part
is necessary only for creating such dll files and requires a preexisting
installation of neuron.

mknrndll files are in the ./mknrndll subdirectory. Before installation
read the ./mknrndll/README file.
