The key to getting CoSessions to work with Windows 2000 or XP is as follows:

Add the following lines to the [386Enh] section of the SYSTEM.INI file before installing CoSessions.

[386Enh]
device=*vmcpd

Once you have made the change, save the SYSTEM.INI file, reboot the computer, and then reinstall CoSessions. Note: You can Edit the SYSTEM.INI file by Clicking on the Windows Start Menu and Select Run. In the Run Dialog Box type sysedit and select OK. Four screens will open. Click on the System.INI screen.
