Can I uninstall Groove Agent software?

I don’t use most of the native instruments like Retrologue or Groove Agent, nor the loopmash…

I want to uninstall any vsts that I don’t need to free up some storage…
Will my Cubase run fine without these storage-hungry VSTs?

Yes, Cubase will run. The biggest part of the plug-ins is the sound library. So Uninstalling of Grove Agent saves some space. Retrologue doesn’t save almost anything.
