Launcher Download Problem (EPERM: operation not permitted, rename)

[Platino]

Sorry for posting this in general, but I seemingly can't post in Support, so I wouldn't know where else to post this.

Every time the launcher tries to download a media file (.avi, .gif, .jpg, etc) this error stops download:

Error: EPERM: operation not permitted, rename 'path/to/file.jpg.part' -> 'path/to/jpg'
Verify your game data by clicking retry.

I've tried giving the launcher admin permissions, and the error still persists.
I've also tried renaming a ton of them, and while I was able to download most of the client (I'm only a few MBs away), with every jpg file being about 10-50KB big I could be here for a long time.

Any known fixes for this?

Update: I slammed a pepsi and a can of pringles and got to renaming. I'd say I had to rename between 40-50 files and re-running the update.
Still, please look into it devs.

See you in game!
