If your current installation is severely corrupted, a clean reinstall is the most effective solution.
Navigate to the installation folder, typically located at C:\Program Files (x86)\Biesse\Optiplanning\ . Update the drivers (the software that reads the dongle)
: Store an unaltered copy of your original Optiplanning installation software on a dedicated offline USB drive.

If you have downloaded the software but lack the dongle, the program will typically not open or will run only in a restricted demo mode.

: As a last resort, set up a virtual machine (using Oracle VirtualBox or VMware) running an older, officially supported version of Windows (like Windows 7). Install Optiplanning inside this safe environment and pass your USB dongle through to the virtual machine.
