To my pleasant surprise I was able to install the Smartlabs SDM3 (308) on Vista 32 bit and connect the SHN Utility to my PLC. Although not extensively tested I have been able to connect the Utility through the PLC to my EZIO8SA and monitor both the analog and digit outputs of two new EZEyes. Also Displayed the link database in a few of my Insteon devices. I was also able to successfully reproduce what Stuart Sweet had already tested in connecting the Utility to my EZSrve. Displayed the link database in my EZIO8SA as well as doing a successful Timer List. I see the same Macro List problem that Stuart found using the base 1.80 version of the Utility.
That leaves the Vista 64 bit compatibility question.
