Okay, I found the right ahsetup.exe (Active Home). It's doing the same thing for me: extracting CloseApp.exe (which is the same program I found) to the temp folder, but then shutting down with an error message about being unable to use it. As to why, the answer, IMO, is that this is a very old program (the download site says it works in Windows 3.1), and most programs that old simply don't work in Wine. I suspect that even if we could get past the installer error, the app still wouldn't work properly--it seems like something that probably relies on Windows hardware drivers, which wouldn't work in Wine. I did, however, stumble across the X10 Community Forum at http://www.x10community.com/forums/index.php , which has a section for Linux. You might want to ask there about setting up your system--there seem to be native Linux apps to control at least some models of X10 hardware.
