You may need to purchase additional licenses. | | Legacy software no longer supported | Consider migrating to a modern alternative. If that's not possible, run the legacy software in a dedicated virtual machine (like VMware or VirtualBox) on a legacy OS where the dongle driver works. This isolates any compatibility issues. | | Testing software on multiple configurations | Software vendors often provide temporary licenses or debug builds for testing and development. Contact their support or sales team. | | Protecting your own software | Use professional licensing solutions (e.g., CodeMeter , Sentinel LDK ) that provide robust SDKs for developers, rather than relying on a dongle. |
