There's one application on my computer, Powerchute Personal Edition, that has not worked (rather, it "seems to be working") since it was installed on a new computer running Win7. Yes, its icon is displayed in the lower right corner of the screen (I forget the corner's name) and, I do receive notifications when the UPS (monitored by Powerchute) switches from commercial power to the internal battery, but I cannot open Powerchute or any of the any of the four functions it monitors. APC (who provides Powerchute) Tech Support, quit responding to my questions/complaints when they could not help. They suggested the 32-bit edition; the 64-bit edition; both refused to run. Windows (one would think) would have found a solution for the problem but only if the "stopped working" message is sent to Microsoft. Any solid ideas?
