DDP2000 Composer lite install procedure
Installation Location
The default installation directory is:
C:\Program Files\DLP Composer Lite
If you want to install to a different directory (perhaps alongside a prior release of DLP
Composer™ Lite), click the "Browse" button on the "Select Features" page..
USB Support - Installation (All Platforms)
This release includes support for a USB communications interface to DDP2000-based
projectors. The setup program includes the files needed to install USB support (for
Win98/WinMe/Win2K/WinXP only -- Win95 and WinNT are not supported).
After DLP Composer™ Lite is installed, to install the USB support, choose the "Install
DDP2000 USB Driver" icon under "DLP Composer™ Lite" in your Start menu.
USB Support - Win98/WinMe Only
Installation on Windows 98 or Windows Me may prompt "Please insert the disk labeled 'DLP
Composer Installation Directory', and then click OK". This message may be safely ignored
by clicking the OK button.
Another prompt will then appear: "The file 'windrvr6.sys' on DLP Composer Installation
Directory cannot be found". Again, click OK and the installation proceeds without further
