Hey there
Downloaded properly via Steinberg Download Assistant.
I have proper License.
I actually uninstalled SL ONE from my system (after Downloading and installing it with Cubase 11).
and still SL ONE opens, and SL PRO is nowhere to be found…
I think the installation file on the server is the wrong file by mistake maybe ? 
There’s only one installer and one software binary for all SpectraLayers editions (Pro/Elements/One) so no need to uninstall - what edition appears at launch depends on the licenses you have activated in the eLicenser Control Center.
Can you see an active SL Pro license there?
If so and if SL Pro still doesn’t launch, can you send a screenshot of the eLicenser?
Ah… Then I probably don’t have a proper license…
Mine is an NFR license.
Is that it?
Red dongle ? There’s an issue with it right now, you have to request a supplementary license to Steinberg. We’re working on that though, so it’s easier to use SL with a red a dongle.
Yes, red dongle.
Thanks Robin, I will ask my local vendor.
If you know how I can request that directly from Steinberg - it will make things quicker I’m sure 
Same issue here.
Any news about the red dongle SL authorization?
The next patch will make it easier to use with the red dongle. No ETA yet, but could be coming this month.
