Corrupt Files While Installing

[pounce]

Trying to return to rohan. I downloaded it from the gamepron option and the gamershell options and both times when I try to install it, it says I have to replace a bunch of files and then it says that there are corrupt files. and it tells me to download from a different place or redownload and try again.
how do i fix this?

my laptop is windows 8 if that matters

You should delete everything in regedit, download the game and install. How to http://www.wikihow.com/Use-Regedit
or you can simply type on the start menu search field regedit press enter, then at the left side look for HKEY_CURRENT_USER > software > delete rohan files or HKEY_LOCAL_MACHINE > SOFTWARE >Delete all rohan files. Download and reinstall the game.

P.S. but before doing the instruction above you should turn off your anti-virus and firewall. This might be causing the files to be corrupted due to restrictions.
