@r0s3ysims I've merged your post with the master thread for the "already running" error. Please see the first post on page one.
For the folders you can't delete, does it help to restart your computer? If not, please list the full path to each folder, which you can see by right-clicking the folder and selecting Properties > General. I'd like the Location.
@r0s3ysims Looking at the screenshot you sent, I have no idea what this folder is for, maybe something to do with Oculus? It's also possible that this is a leftover pointer or some other empty bit of data. Regardless, Sims 4 wouldn't be reading the folder, so you can ignore it.
