Hello!
I use the VST “korg legacy cell”. On my 64bit Notebook it works in renoise, on my 64bit Workstation it dont, error message: failed to initialize the plugin ‘vst: korg: legacycell’.
I uninstalled the 64bit version and tried the 32bit version, also i deleted CachedFailedVSTs_x64 and CachedVSTs_x64 in the right version user folder.
Please advice to solve this riddle.
Thanks for answers!
I think that you cannot use Korg Legacy softwares on 2 computers at the same time, since Korg seems to permit to use it on 1 computer only.
So if you want to use it on your Workstation, you have to delete it on the Notebook and re-authorize it on the Workstation, probably. 
its only one specific vst in the legacy collection which not work on two pc’s, i have legally activated the stuff on two pc’s, a third one isnt allowed.
Ohh sorry, I had misunderstood the KLC licence policy. Now I’ve found this Q&A on Korg User Net;
Q7. Can I do license authorization for multiple computers?
A7. You can install and authorize the software on multiple computers, but you can only utilize the software on one computer at a time.
So indeed, you should be able to open LegacyCell on your Workstation PC too.
But according to your posts above, I don’t know why LegacyCell doesn’t work on the specific PC at all. It’s quite strange… 
Maybe, you had better report and confirm this issue to Korg support, since LegacyCell is somewhat unique VST comparedwith other 5 synths. It doesn’t need authorization itselfbut insteadit needs that MS-20 / Polysix /MDE-X are installed, doesn’t it?? 
Maybe there is a compatibility problem between your PC spec and suchcomplex VST.
:excl: [Edit]
Btw, are you really sure that MS-20 / Polysix / MDE-X are installed on your Workstation PC too?
I personally have KLC digital edition only and when I’ve tried to install LegacyCell from Korg User Net, I’ve seen the same error message of your first post. That’s natural because I don’t have MS-20 and Polysix on my PC.
