M98 = applies to MIDUSS 98

M98
][
V2
] I want to install the new Version 2 on the
same PC as my older MIDUSS 98 installation. I still want
to use MIDUSS 98. Will Version 2 interfere with MIDUSS 98 and
vice-versa?
Both MIDUSS 98 and Version 2 will co-exist on the same PC.
The installation porgram for Version 2 creates a new install
folder. Both versions will not interfere with each
other. You should be carefull locating and using your
working files for each version. Version 2 data files
will not work with MIDUSS 98, but MIDUSS 98 files will work
with Version 2. See
this link for
more compatibility information.

M98
] I have downloaded the latest Setup
program from the MIDUSS web site and want to update my old
version. What must I do to preserve my license authorization?
Should I run Uninstall from the Control Panel? Should I erase
the entire \Miduss98\ folder? Should I use the license transfer
procedure before and after running Setup?
Running Uninstall or
erasing the \Miduss98\ folder will cause your current license
authorization to be lost, so do NOT do either of these. Using
the license transfer procedure (see Appendix 'B' in the User
Manual) is necessary only if you intend to install MIDUSS in a
different folder or directory from the one currently used.
The best way is simply
to run Setup and install the new version in the same folder -
e.g. \Program Files\Miduss98\. The new version will inherit
the license authorization attributes created for the previous
version.
Of course, if all you
want to do is update the executable 'Miduss98.exe' it is
faster to download the compressed, self expanding file
'm98v100.EXE', place it in the \Miduss98\ folder and
double-click on the file to overwrite the file
'Miduss98.exe'. You can make a copy of the old one if you
like, in case you want to restore it. Use Edit|Copy and
Edit|Paste to make a file called 'Copy of Miduss98.exe' and
(optionally) rename it as 'Miduss98Jan26.exe' using the
appropriate date, of course.

M98
] I can't run the Tutorial lessons from the
CD but MIDUSS complains that
these files are 'read only'. What should I do?
This is the result of
an error in the September 4, 19version of the program. There
are two ways to fix this.
(a) You can copy the
files from the CD on to your hard-disk.
(b) Down load an
update for Miduss98.exe in the form of a self-expanding file
'm98v100.EXE' from this web site. Place the file in your
MIDUSS folder and double click on it to expand it to replace
the existing executable Miduss98.exe

[
M98
] When I try to run MIDUSS
I get a fatal message "Crypkey -102". Help!
This error means that
a required server is not running. It almost always means that
you have loaded MIDUSS on a computer using Windows NT (version
4.0 or later) but you have not installed the secondary setup
program to set up the NT Service. To install the missing
driver insert the CD in the drive and double click on the file
'CrypkeyService.exe'.

[
M98
] The Authorization Information window shows
the License Status as "Authorization NOT Present" even after I
got my Key Code. When I pressed [Change Authorization] the
Site Code had changed. What's going on?
This was an error on
the first batch of CDs and early versions of the 'update' file
m98v100.EXE. In fact authorization was
present and the program could be run normally by pressing [Run
MIDUSS]. This error has been corrected as of Nov. 20 1998

] Why is MIDUSS a better
design tool than HEC-1?
There are many
programs available for simulating stormwater management.
However MIDUSS is probably unique in offering the capability
of designing different components of the stormwater system.
Programs such as HEC-1 (now known as HMS or Hydraulic
Modelling System) are useful for simulating the runoff from a
given system when subjected to a particular storm. However the
design capabilities are very limited.

V2
] Why is MIDUSS superior
for design to SWMM?
SWMM is the
pre-eminent program for modelling both quantity and quality of
runoff from a catchment. However the design capabilities are
limited to trial and error efforts and for each trial a
complete simulation is necessary. SWMM does not have the
interactive capabilities, which is the leading feature of
MIDUSS.

[

][
V2
] Can MIDUSS run in batch
or interactive mode?
MIDUSS can do both.
Interactive mode is described as a manual run and you can
proceed from the upper limits of the drainage network
simulating the runoff from each catchment and interactively
designing the capacity of each element of the drainage
network. Once a design has been completed you can repeat this
in batch mode by using the output file in Automatic mode. This
allows you to repeat the design subjecting it to a more severe
storm without having to re-enter all the commands and data.

][
V2
] Why is there not a file
save command
like other Windows programs?
MIDUSS automatically
saves the commands, data and some of the results to the
current output file. There is always a current output file
available to record this information. It is recommended that
you specify a job specific folder to contains these output
files, but if you neglected to do this the data is stored in a
file named DEFAULT.OUT in the MIDUSS program folder.

M98
] How do I use the multimedia tutorials on the
MIDUSS CD?
From the Help menu,
clicking on the Tutorial menu item will open a small window
which prompts you to setup the list of available lessons. When
you click on the setup button a dialog box will appear
prompting you to navigate to the CD reader and the Tutorials
folder. Clicking on any of the files in this folder will
populate the tutorial list box with all the training files in
the folder. You can then select a lesson and play it with the
[Play] button.
-
[

][
V2
] When I select a training
tutorial from
the list I see the lesson but I have no audio but I have a
headphone jack on my CD. What is the problem?
The audio track can be
heard only if you have a sound card installed or built into
your PC. The CD output jack is for music CDs only.

V2
] My monitor is 800 x 600
resolution. How
can I get the various MIDUSS windows to be more organized on the
screen?
We strongly recommend
a minimum resolution of 1024
x 768 to use MIDUSS comfortably.

[
M98
] I recently
defragmented my hard disk and now MIDUSS does not work.
What happended?
Many tools exist
to correct fragmentation of your hard drive. These work by
moving the clusters comprising a file to be contiguous. If
this operation causes the MIDUSS license authorization
files to be moved you may lose the current authorization. The
files created when you authorize MIDUSS98 are as follows:
Miduss98.KEY Miduss98.ENT Miduss98.41S Miduss98.RST
The Microsoft defragmentation programs that
come with your Windows operating system will always recognize
these files as 'System' files and will flag them as
'unmovable'. However, other proprietary programs such as
Norton SpeedDisk (version 6.0) and a defragmenter by 'Nuts &
Bolts' (and possibly others) may require that you define the
files as 'unmovable'. In general, if you run a
defragmenter on a regular basis, we recommend using the
Microsoft version that comes with you operating system.
If you are uncertain about the procedure you
can prevent this from happening by transferring the license to
another drive or another machine before running the
defragmentation program. When finished you can transfer the
license back to the original machine. However, you should not
do this too frequently as it is both time-consuming and a
little risky if your floppy disk drive is less than 100%
reliable.
