I got my free copy of Prince of Persia: The Sands of Time. It installed just fine, but upon startup it'd show a window with "The local sound file is missing please see Readme.txt file for technical support." and quit.
Googling didn't help, so I started looking around.
I found it interesting that there were soundlocal.big and soundlocal.fat files under the Support\inst\data\EN game subdirectory, but there was only soundlocal.fat under the Sound subdirectory. And indeed copying the missing file to Sound fixed the issue.
I'm not sure what happened, but there wasn't much space available wile I was installing it. Perhaps the installer didn't do a proper job of assuring there was enough space and this file got lost as a result.
So far this was the only issue, the game ran smoothly from then on, but after five minutes I found out I don't like the game at all and wiped it :-)
