Version 2 Compatibility
General
Version 2 Network and Version 2 Single will co-exist with older versions of MIDUSS on
the same computer. These older versions are MIDUSS 98 and MIDUSS 4.72
for DOS.
Version 2 Single will not co-exist on the same computer with
Version 2 Network installed either as server or client.
Version 2.0
Data files
Early Version 2 text output files are fully compatible with later
updates to Version 2. That is, an early output file created in Version
2.00 Rev. 100 will work in Version 2.65 Rev 400 (for example).
A text output file created in a later release (example) Version
2.65 Rev. 400 will work in earlier releases, Version 2.00 Rev 100 for
example, with the warning that any new field data in the newer output
file will not have a suitable location or use in the older release and
so that newer-type data will be ignored. Version 2 introduces the Save
Session feature which is a snapshot of all interactions with MIDUSS.
Sessions are saved in a binary file (with the .bin extension). As with
the text output files discussed above, older Session files are
compatible with updated releases of MIDUSS Version 2. However, a
Session created with a recent Version 2 will be compatible with older
Version 2 releases to the extent that new features (on the new Session
file) cannot be properly assigned in the older release and will be
ignored.
Program Upgrades – Single to Network
A Single license cannot be updated to a Network version. The Single
license must be completely uninstalled first.
Program Upgrades – Demonstration Mode to Network
A Demonstration Mode license cannot be updated to a Network
version. The Demonstration license must be completely uninstalled
first.
Program Upgrades – Demo to Single
A Single license is the same as Demonstration Mode license in terms
of files and installation procedures. All that is needed to upgrade
from a Demonstration Mode to a Single version is the addition of a
Serial Number on the opening screen.
MIDUSS 98
MIDUSS 98 data files (the output files) can be used in Version 2
Network and Version 2 Single.
Once the older files have been processed by Version 2 the new
output files cannot be used again in MIDUSS 98. MIDUSS Version 2 data
files will not work with MIDUSS 98.
MIDUSS Version 2 data files will not work with MIDUSS 4.72 for DOS.
MIDUSS 4.72 for DOS
MIDUSS 4.72 for DOS data files (1986-1998) will not work with MIDUSS 98 or
Version 2 licenses.
