EMP NS Connection failures caused by Remote Control applications
Subject:
This bulletin was created to inform you of an issue that can occur when using the PowerLite
735c/7850p, 8300i (with EasyMP.net module) and remote control software.
Description of Issue:
The user attempts to run EMP NS Connection on Windows 98SE/Me/2000/XP with the PowerLite
735c/7850p/ 8300i (with EasyMP.net module). When the EMP NS Connection application is
launched, it immediately gives an error message stating that EMP NS Connection "FAILED TO
INITIALIZE."
Reason:
Epson has found that remote control software, like PCAnywhere and RealVNC, causes a conflict
with the EMP NS Connection application. These remote control applications use a "Video Hook
Driver" that conflicts with the Epson GDI Monitor driver that is installed and used by EMP NS
Connection. Most remote control programs load a small client application at Windows startup and
leave an icon in the system tray (located at the bottom right on the desktop) to indicate they have
been loaded. In most cases, the remote control software can be turned off by right-clicking on the
icon in the system tray and disabling or exiting the program. Remote control applications do not
have to be removed from the system in order for EMP NS Connection to run properly; they just
need to be turned off. Consult the documentation that came with the remote control software for
information on how to disable the software from automatically launching every time the computer is
started.
Once the remote control software has been turned off, EMP NS Connection should run without
returning an error. If you continue to have issues connecting to the projector, consult the EMP NS
Connection Help file or User's Guide for troubleshooting assistance.
Notes:
VNC stands for Virtual Network Computing. It is a remote console utility which allows a user at his
computer to assume control of another computer across a network, as if they were sitting in front of
that computer.
