Thank you LG for the offer. In the forum I have found similar problem with the old eLicenser that worked on older operating systems but doesn’t work on Win10. It recommended to install the latest version of the eLicenser Control Center software. So I have uninstalled the old version that couldn’t validate registrations. Also uninstalled already installed “Steinberg MP3 Upgrade Patch”.
Then installed the latest version of the “eLicenser Control Center”. And again installed “Steinberg MP3 Upgrade Patch”. Entered activation code an the operation was successful. Now WaveLab Elements 8 can save PCM set as mp3 files.
But now I’m interested if I can upgrade my WaveLab Elements 8 (Version 8.0.4 (build 701) - 64 bit) to the latest version of WaveLab Elements or not Elements. Or is it possible to upgrade to some later version without paying?
