Just found this, it may work.
Problem: I can't install CoSession 7.0 on WinNT 4.0 or Windows
2000. Every time I try, I get an error saying something about
"No 'keyboard.drv' or 'device=' entry in the system.ini.
Solution: Add the following lines to the SYSTEM.INI file, usually
located in the C:\WINNT directory.
[386Enh]
device=*vmcpd
Once you have made the change, reboot the Windows NT system. Now
try installing CoSession 7.0.
