Hello, is it necessary to update the Dolphin 5.0-16101 to the most recent 5.0-17995 edition? If so, dolphin is saying a new version is available but it isn't allowing me to update it, saying "Failed to write to directory despite administrator privileges." I've been playing ZTP HD 1080p in the ZTP4K Standard Edition. Its been choppy in audio and visually so I'm trying to figure out all I can to get it to work smoothly. Looks amazing.
