Can I delete contents from the Downloaded Installations folder?

I believe they are part of a dell system update package, I believe it has to do mainly with Dell Mobile Connect which is fficially no longer supposed to be installed (according to Dell, it doesn't seem to have major problems, just a few things are weird), so you may lose Dell Mobile Connect also. I'm considering doing this myself as I'm having a time getting anything but AWCC (Alienware Command Center) from like 5 updates ago to install successfully, and after installed it shows the starting logo, then never starts up. Well good luck to the both of us eh? lol IF either of us find a solution please come back here and share! There's very little on this topic that isn't like the same few things everyone's saying.
