Read this user's problems getting Silent Hunter III to install in Windows...
"The documentation that ships with Silent Hunter 3 is quite lacking. Additionally, over time players have shared many insights that are worth repeating."
So, it's poorly documented....
"I walked through installation, but was disappointed to find I was required to install Adobe Acrobat Reader 7 (Im still happy with 5) and Windows Media Player 9 for the documentation and ingame videos, respectively. I imagine Acrobat 7 is not really necessary, but I didnt mess with it. The installation for WMP 9 failed because I do not have IE 6 installed, or so the Silent Hunter III installation claimed. I later installed WMP 9 manually and IE 6 was not necessary."
...and has dependency problems...
Hmmm...interesting!!!
