Instructions on how to transfer CALYPSO license and dongle to a new PC.

It is standard with PCs shipped directly from ZEISS, that the dongles are stored inside the PCs.

Here are the steps to transfer the license from one PC to another:
1. On the old PC, head to C:\ProgramData\Zeiss and find the folder called “License”
2. Copy this entire folder and paste it to the same location on the new PC.
3. The last step is to move the dongle to the new PC.
