ProjectoWrite2 / LightPen Software FAQ’s
Q: When I start up the LightPen program, I get the message “Being unable to find the LightPen system, the program cannot run normally, please connect the USB of the LightPen system with computer, and run the program.”A: Shut down the LightPen program. Make sure the USB is connected between the computer and the projector. Restart the program. If you still get the warning, you may have to deactivate the built in webcam of your laptop.
A: Also make sure the USB cable is rated at 2.0 or better and the length does not exceed 5M without a USB amplifier.
Q: When I start up the LightPen program, I get the message “Sorry, the local language is not supported, application will execute in English.”A: Click OK, program will run normally.
Q: When I start up the LightPen program, I get the message “Error: Common Library – Path.”A: There is an error in the LightPen program finding other parts of the program. Remove the program from the desktop. Save the LightPen2 folder into a folder on the hard drive. Open the folder and make a shortcut of the LightPenII.exe file and copy to the desktop.
Q: When I start up the LightPen program, I get a web cam window and a message of too much light.A: Reduce the infrared light in the area: draw curtains/blinds, turn off lights, and change the orientation of the projector (aim a different direction away from the light source.) The webcam preview pane should be black if there is no IR source, an IR source will show up in the preview pane. In addition if you are not able to solve the problem this way there is another option. When you open the LightPen folder on your hard drive there is a setting file in WordPad. Open this file and you will find a list of settings. Towards the bottom there is a line “CheckEnvThreshold”. Close the LightPen2 software; try increasing this setting from the standard 210 to 220. Save the file where it is on your PC and then try to run the LightPen2 software again from your desktop. If this does not fix the problem close the LighPen2 software and try adjusting the “CheckEnvThreshold” by adding another 10 to make 230. Continue to do this until your problem is resolved. If you have reached 300 please call BOXLIGHT tech support at 866.972.1549.
