This is version 1.01 of Logitech's GamePanel Software for the G15 keyboards (gaming or not). It is probably the only version that will install on Windows 2000 (aside from v1.02), and version checks written inside the installation script also identifies checks for Windows 95, 98, ME, and NT 4.0 SP6. Will work on XP and Vista, but Vista support is minimal. Tested on Windows 2000 to satisfaction. Archived directly from Installation CD. 32-bit version only.
