Using the version table
Many programs designed to run with a previous version of MS-DOS will run
correctly with Windows NT. In some cases, however, a program might not run correctly
unless its name is included in the version table. The table indicates to the
program that it is running with the MS-DOS version for which it was designed,
even though it is running in the MS-DOS subsystem. By interpreting MS-DOS version
5.0 as the earlier version, the program will probably run correctly; however,
using setver will not solve the problem if the program is not compatible with Windows NT.
Loading the version table into memory
Before you can use the setver command, the version table must be loaded into memory by a device command in your CONFIG.NT file.
Restarting after updating the version table
When you update the version table by adding or deleting entries, you must
start a new command prompt session to reread the version table.
Updating existing entries
If you specify a filename that is already in the version table, the new entry
replaces the existing entry.
