I have Installed Kirby Alarm v2.11
I can't help with the original question, but, you appear to be using the last free version (Web site checked 2019-01-14):
Kirby Alarm & Task Scheduler
Kirby Alarm Pro (v4.45)
File Size: approx 6.5 MB | Date: April 13, 2008, 9:49 pm
Kirby Alarm Pro Lite and Kirby Alarm Pro are the same program, but with some of the more advanced features disabled.
Kirby Alarm v2.11 (Old free version)
File Size: approx 2.47mb | Date: February 10, 2015, 6:52 pm
Old free version of Kirby Alarm v2.11 originally released in 2004.
I don't know why the file is dated 2015 if it's for a 2004 program. But... maybe a program that old doesn't play nicely with late-model Windows? The current Pro version - now 11 years old
itself - works fine on Vista Home Premium, but I haven't tried it on anything later. Maybe time to consider registering, or an alternative program?
