Hi, I have a big problem with the software WinsealXP and LaserDRW When they

I have a big problem with the software WinsealXP and LaserDRW
When they start they say “USBKey is not pluged”
To be more detailed I give you more details :
I purchased a jk-k3020 laser co2 40w provided with a Lihuiju Studio labs HT-MASTER-5 Nano mainboard dated 2015-06-05
I set the ID from the mainboard to the control software and I can communicate with the machine to set the starting position, speed, make a preview…
The problem is when I try to engrave a project : WinsealXP 2013.02 says to me that “USBKey is not pluged”. It display the same message when it start and also if I click on Help.
When I insert the USB Dongle (B model) in the PC (I tryed with 3 different PC with Win7, WinXp and Win8) the operating system install correctly the new hardware with no errors, the USB Dongle light up (blinking led) but the software cannot recognize it… (see photo)
Any idea ???
Best regards


That key does not work with winseal, but it should work fine on laserdrw

Like Sean said^^ You need the red USB key(C- Lock) to work with winseal LaserDRW and Corellaserl. You have the B-Lock key which only works with Corellaser and LaserDRW. The Blue USB key (A-Lock) will work with Winseal only. Here is a link to their web site. Look at the top of the page. It will explain what the different USB keys work with. http://www.3wcad.com/

The B Lock should also work with LaserDRW.

The key I have with LaserDRW looks exactly like the one in the picture.

I solved !!!
After your comments I have installed only CorelLASER and it works so thank you very much !!!

Can you operate the Laser Engraver fully from CoralLaser?

Hi, How did you get an ID from the main board?

Actually only Lihuiyu USB C Dongle works with CorelLaser & LaserDRW & WinSealXP.
