I just bought this game on discount. Installation went OK. Setup was difficult with three freezes and crashes before my video card was detected (ATI Radeon 9600). Then, every time I hit the play button the game is asking to have the original Summoner CD in the drive and refuse to start. I got around the problem by going into the installation folder and using "Sum.exe" instead of "Summoner.exe" that was the original link to the Summoner's Icon installed by default. Note that this bypasses the setup screen (Although it can still be done through the "Option" menu item) and thus you may have to initially use the default "exe", do the setup and then change the icon's link to "sum.exe".
