im download file torrent and follow this step
Simple step-by-step guide
1.Extract DISK1.mdf and DISK2.mdf (DO NOT extract the .mds file!) from .rar archive(s) to e.g. C:\Downloads\SBPR
2.Extract the content of both .mdf files (using 7-Zip or WinRAR) to e.g. C:\Downloads\SBPR\setup, overwriting existing files. You should end up with five .cab files in there.
3.Start setup.exe. The locale doesn't matter in this case, since the installer supports Unicode now.
4.Click (N) a few times and wait while the setup installs.
5.Run InitSettings.exe in the game folder to change resolution and picture quality in accordance with your preferences and hardware.
6.Once you're satisfied with video options, you can skip the launcher and run the game or poser directly from the appropriate executable (SexyBeachPR_32.exe, SexyBeachStudio_64.exe etc.) in the game directory.
