YBK Audio’s Instrument Player uses a single-use license code that activates one computer once and cannot be transferred afterward.
The code is spent when it activates online. Reinstalling the app does not turn it back into a fresh key, and moving to another computer is not treated as another installation of the same license. YBK sells the paid version for $10 as a one-time purchase rather than a subscription, but the low price comes with a fairly strict machine rule.
The Instrument Player free launch license follows the same one-computer idea. Claiming it during the free launch month gives you a permanent license for the machine where you activate it, not a portable seat you can shuffle between a desktop and laptop.
Several common hardware swaps are treated the same way. You can replace the drive, RAM, graphics card, or monitor and keep using the existing activation. Changing the network, Wi-Fi adapter, or VPN also leaves it alone, which matters if you rebuild the storage side of a music PC or change networking gear without replacing its core hardware.
The practical wrinkle comes after a clean Windows install. Instrument Player may still recognize the licensed machine, while your VST3 instruments themselves have disappeared because their installers, files, or vendor activations have not been restored yet. If the app opens but a synth does not return, the missing VST3 troubleshooting path deals with scanning separately from the Instrument Player license.
Hardware-linked activation is not unusual as a technical model. Machine-bound software licensing can identify a device through a fingerprint assembled from machine characteristics and compare later launches with the stored identity. YBK publishes the practical boundary for its own implementation, which is more useful to buyers than guessing which component secretly matters.
A new virtual machine also counts as a new machine under the license terms. Creating another VM is therefore not a workaround for keeping one activation alive across several environments. The code cannot be transferred, reissued, shared, or used for a second activation after it has been spent.
This rule belongs to Instrument Player, not Windows itself. Windows has its own digital-license behavior after hardware changes, and Microsoft provides reactivation routes for some Windows licenses after a motherboard replacement. Getting Windows activated again does not override YBK’s separate rule that a replaced CPU or motherboard requires a new Instrument Player purchase.
There is no deactivation button described for moving the YBK license before an upgrade. If you already know a motherboard or CPU replacement is coming, assume the old Instrument Player activation stays with the old machine identity rather than expecting to release it and carry it forward.
Updates released from October 20 onward belong to purchased licenses. Buying Instrument Player includes every update in the 1.x version line at no extra charge, while a future major version may be sold separately. The paid license is still one machine and one activation, so paying does not turn it into a transferable seat.
Losing the email is less serious than losing the machine entitlement. YBK says launch-month users can enter the same email address again to receive the same code, while paid users can contact the company from the purchase address with their order number. Recovering the code only recovers the credential, though. It does not reset a code that has already activated a different machine.
The clean distinction is between changes around the computer and changes to what YBK considers the computer itself. Drives, RAM, graphics hardware, Windows reinstalls, networking, and ordinary updates stay on the safe side. A new CPU, motherboard, physical PC, or VM crosses the line and needs another license.

A Windows reinstall does not create a new licensed machine
Wiping Windows sounds drastic, but YBK explicitly says resetting or reinstalling Windows on the same computer does not end the Instrument Player license. Windows updates, driver updates, and Instrument Player updates are also allowed without consuming another activation.Several common hardware swaps are treated the same way. You can replace the drive, RAM, graphics card, or monitor and keep using the existing activation.

CPU and motherboard changes count as a new computer
YBK draws the hard line at the processor and motherboard. Replace either one and Instrument Player treats the result as a new computer, so the original single-use license no longer covers it. The same applies if you move the software to a different physical PC.A new virtual machine also counts as a new machine under the license terms. Creating another VM is therefore not a workaround for keeping one activation alive across several environments. The code cannot be transferred, reissued, shared, or used for a second activation after it has been spent.

Free and paid licenses keep different update rights
The launch offer has another limit that is easy to miss. A free license claimed during the launch month keeps working permanently, but it includes only the Instrument Player updates released through October 19, 2026. YBK says the free license remains usable on the last version it received during that period.Updates released from October 20 onward belong to purchased licenses. Buying Instrument Player includes every update in the 1.x version line at no extra charge, while a future major version may be sold separately. The paid license is still one machine and one activation, so paying does not turn it into a transferable seat.
