Those files don't appear to work with Vista Ultimate 64. I can't get the game to even begin the installation process. I've tried running in XP compatibility mode and I tried uploading the files from the update on the HPS site, but none of those things helped.
By the way, the update is very poorly done. For starters, the instructions say to upload three files to correct the problems with Vista. Unfortunately, there is no link to these files. The only zip file available is the one that leads to the DLL OCX Patch File, which includes 8 or so "missing" files. But the Vista fix says only to use three. Which three?
At any rate I'm not sure missing sound files are the problem as the game doesn't even try to install. As soon as the installation process begins I get a message stating it is checking for previous installations, then the entire process stops and goes back to desktop without doing anything.
P.S. This is the very first game I've had a problem with using Vista Ultimate 64. I have a huge number of games of all kinds installed, and not one has failed yet. I've found Ultimate 64 to be much more stable than any version of XP or Vista 32.
