Dsetup.dll - could not find this item

[Trelaboon]

Hey guys, my computer recently had a strain of bad luck and is out of commission. I decided to try installing EQ on my daughters laptop in the meantime but I'm having issues.

Mostly, it's a Dsetup.dll issue - I've had problems with my avast quarantining it before and having to go in and make an exception, but this time, as soon as I download the patch files and extract them, then try dragging them to my EQ folder it disappears, and then says "item not found - This is no longer located in C:\Users\Matthew\Downloads\P99Files36. Verify the items location and try again."

I tried disabling Avast completely and it's still happening so I have no clue what's causing my issue. Anyone familiar with what is happening? I've been away for about 4 months without Internet access and now that I'm home im dying to play, but can't get this sorted out.

Any help greatly appreciated! Thanks!
