I downloaded a program "open any file" from the Apple Store. I tried it on several files and rather than opening them it suggested other programs. It did this many times before I decided to uninstall it. My 2012 iMac said that the file could not be uninstalled because it had open programs attached. I rt. clicked on the app and it had 6 programs attached. As one of the new Macintosh wannabe'z and a Windows user, I am not sure how to handle this problem. I have looked on line and tried several options to remove 'open any file'. I have contacted the owners by e-mail- they have ignored me for 4 days. If you are familiar with this application please help. Thanks
