Hi,

To me it looks like a permissions issue. I would try to install the plug-in as administrator.

hi martin this doesnt let me do it im still getting the same error

it looks like cubase is constantly running in the background on my computer when i start my computer.
if i start steinberg downloader it pops up cant update mediabay because cubase 13 is running…the box to close it is blacked out.
if i open taskmanager it shows c13 is running but it shouldnt be because ive not started it so i think this is the reason i cant update any vst3 plugins because it seems c13 is running.

what can be causing it too start on its own?ive not changed anything on my pc.

Hi,

Try to force quit Cubase from the Task Manager, please.

hi martin its not showing up in task manager.

when i use steinberg downloader its saying theres a update too mediabay (this box appears as downloader is updating)
then a box appears saying please close c13 but its not running…i open task manager and no steinberg products are running except download manager.
