Installing 1.5 problem

[mxstar267]

Every time I try re-installing the 1.5 version and i get to the point where i need to choose a file to put it in, I can never click "Next >" because it is white and it wont let me choose a file. I have already erased my previous downloads and im about to go crazy.

It expects the folder you select to contain a file named "zzzz.saf". If that file isn't there the game won't work.
