Identify Your USB Key
Perhaps you have numerous software dongles and somehow they get all mixed up, or you haven't needed to use your USB key for some time.
Whatever the reason, it can be difficult to keep these things organized.
All Isadora USB keys have the letters ZOMKQ written on them.
The text will be printed on the USB key (not embossed).
If the red light (LED) on the USB Key does not illuminate when you insert the key, this usually indicates that the drivers are not installed.
Download USB Key Drivers
- Go to our Get It page
- Under the "RELATED DOWNLOADS" section, find "USB Key Driver (Required if you use a USB Key)"
- Click on the Mac or Windows symbol to right (as appropriate for your operating system).
- Download the drivers.
- Restart your computer.
Still No Red Light?
If it red light does not illuminate after installing the most recent drivers and restarting your computer, then the key itself might be damaged. This is quite rare unless the key has been physically damaged. If you think the key might have stopped functioning, it is a good test to try the USB Key license registration process on a different computer. If you still can't get the USB key light to illuminate, then your key may have stopped functioning. In that case, you should follow the instructions in this support article. (Also, make sure it is the key that you bought from us. All Isadora USB Keys have the letters "ZOMKQ" written on them. If you don't see those letters, then it's not an Isadora USB Key!)
Red Light But Can't Register?
The first time you use the key on a given computer, you'll need to enter a special six-line registration code. These six-line registration codes are/were sent to you when you purchase(d) a new USB key license, when you upgrade(d) a USB key license from an older version of Isadora to the newest version of Isadora, and when you purchase(d) a Crossgrade to convert a Isadora 2 Standard Edition for Mac/Windows license (Isadora 2) or an Isadora 3 Perpetual License to a USB Key License.
- For Isadora 3, the same six-line registration code will work for both Mac and Windows.
- For Isadora 2, there are separate six-line registration codes for Mac and Windows. (Make sure you use the right six-line registration code for the operating system you're using!)
