An installation problem

[vax2.concordia.ca]

I just received my copy of Nota Bene 4.5 and while the installation
of the two main disks went reasonably well, although I did receive
a message to the effect that the performance would not be optimal,
the installation of Ibidem is impossible. When I attempt to install
Ibidem from the Nota Bene directory in the C drive, I get the message:

out of environment space
ERROR - Please run A... from your Nota Bene directory.

But I am doing that, and in addition, I have added the appropriate
lines to my config.sys and autoexec.bat files, in order to ensure
that I am using extended memory.

I have 16 megabytes of memory on my machine. I that enough?

What am I doing wrong here? Please reply to my e-mail address,
if you think that this is too simple a matter for advanced users.

Thank you in advance.
