DOS Install failure - copy c:\montel\install\unzip.exe (null)\unzip.exe

When running form a DOS only computer and installing MonTel, the installation program will fail to copy any of the files, and stop with an error message "copy c:\montel\install\unzip.exe (null)\unzip.exe"

MonTel install uses the UNZIP.EXE utility, and copies it to the temporary directory, as specified in TEMP DOS variable. This error is unlikely to occur in Windows DOS boxes, as Windows will have set up a temporary directory.

To fix this issue:

From the DOS Prompt enter:

SET TEMP=C:\TEMP

(note that there are NO spaces around the = sign), and

MD C:\TEMP

to actually create the temporary directory. MonTel should now install correctly.

You might want to add the SET TEMP=C:\TEMP to the AUTOEXEC.BAT file.
