After 15 years on a Mac, I'm the happy but woefully ignorant recipient of a Sony Vaio PCV-RX551 (1.6/80) running Win XP. To my huge disappointment, this spiffy new computer won't install games, specifically Baldur's Gate II Shadows of Amn and No One Lives Forever. I got an error 0x80040707. In a search of this error # on Google, it looks like it's related to InstallShield, but what do I know? Nada. Thanks in advance for any assistance.
