I currently have all the patches downloaded and in the correct locations, but when the FFXIV updater goes to install the first one (in this case: H2010.08.30.2000) it errors at around 90+%

I'm currently running Win 7, and I don't have access to beta site since I don't have a key yet.

any advice on getting the installation to go through?

EDIT: It seems the problem was that MSE was falsely flagging a file that the updater needed, "allowing" the file allowed me to complete installation.

File was: file:C:\Program Files (x86)\SquareEnix\FINAL FANTASY XIV Beta Version\data\8C\D3\00\2D.DAT.tmp2
