Please do not use the ARP2600V & MiniMg-V folders! There are here for internal process only. They will be hidden in then future, considering the amount of issues due to their visibility.
If you don't own these synths, do not install them; if already done, please delete them.
Without any license they won't run, and will possibly cause host sequencer failure, and your hamster could die.
Now for the Laboratory, make sure your license appears in the eLicenser Control Center.
If any doubt, just write an inquiry to the Technical Support (through your
account).
