My friend keeps getting this error message: There was an exception! Make sure you don't have the game running, or have any game files opened, then try running the installer again. If this still happens, please pass this error on to Jineapple: boost::filesystem::file_size: El sistema no puede encontrar el archivo especificado: "C:\Program Files (x86)\Steam/steamapps/common/Age2HD/resources/_common/drs/gamedata_x2/51131.slp"
He has the game closed, Steam opened, has the original games on Steam and follows to the letter the tutorial on youtube by Memb.
He has tried with and without ticking the various optional boxes in the installer.

He of course has the 1.5 Beta installed and plays with it.

We tried with Voobly closed and/or working.

see if this helps

Sounds like the Steam installation is missing that file - Make him verify his game files (right-click age2hd in the steam library->properties->local files->verify game files), then try again.
