Dawn of War Codex

It says:

"Error opening file for writing:
c:\program file x86\steam\SteamApps\common\dawn of war ii - retribution\Elite\,\Archives\Elite_attrib.sga

Click Abort to stop the installation,
Retry to try again, or
Ignore to skip this file"

If I ignore it, of course, afterwards it does not work because it occurs to several files ...

I have no idea what is the problem, not the first time I have installed this mod ...

Well, I reinstalled the game and it worked afterwards
