I don't know if I understood you correctly, but you do realise that between uninstalling and reinstalling you have to clear sufficient space on your drive for the game? Although 5MB does seem a weirdly small amount.

Then I can only imagine that for the installation the game needs a temporary staging area, probably on your C-drive.
I'd imagine that clearing a few MB on C could solve it.
