Cannot open or uninstall a program

I just installed Win 8, Chameleon Clock, a reminder program that pops up when an appointment is due, will not open, when I try to uninstall it, I get the

message that the program is open and must be closed to uninstall, cannot find it to close it, another WIn 8 nightmare, used this program for years without a

problem, any help appreciated.It was always hidden in the start menu, when putting the cursor on the start area it would pop up, now nothing

I take it you’ve tried rebooting?

If so, and the program is set to start when Windows starts, go to Task Manager, Startup tab and find the program there. Disable it.

Reboot and uninstall.
