How to activate iZotope plug-ins in Sound Forge Audio Studio 10.0 bundle? Authorization requires a serial number but I haven't got any.
The current version of SoundForge Audio Studio is 14 - version 10 is quite old now and likely goes back to when Sony owned that product. When did you buy version 10 and from which website/company did you buy it from?
If you bought version 10 from Sony probably back in 2016, your purchase confirmation email should have listed the iZotope serial number/s for any iZoptope plugin that shipped with version 10 at the time. If 10 was a typo and you meant version 14 and you bought 14 directly from MAGIX, you would need to contact MAGIX to sort it out for you.
Sound Forge 10 was SCS (Sony) product.
I do not recall which iZotope plug-ins were included with SF Audio Studio-10, but as @condex stated, they would have a separate serial number.. and activated though iZotope. If they were activated before, the plug-ins can still be downloaded and re-activated though your iZotope account, obviously you need your iZotope log-in username (email) and password.
