Is ALNET compatible with Windows VISTA?
Alnet version 3 is now mostly compatible with Vista. The only system that is still troublesome is the 16CH Real time systems based on the RTD cards. All Pro, Netstation and DSP will work on Vista. Raicom still recommends though that Windows XP is used where ever possible due to the maturity factor of the OS compared to Vista which is still considered by many IT specialist to be unstable. In security situations, stability is much more important than flashy start buttons and fading windows.
