I was having some trouble with BBEdit on one of my machines, so I decided to delete and reinstall the application. That’s not very difficult in ordinary circumstances, but since I bought from the App Store, it should have been even easier. There should be no need to enter any license information, just a click and install.
First, I deleted the app. I deleted BBEdit from the applications folder. Somehow, it was still in Launchpad. So, I deleted it from Launchpad. Surely that would be enough.
Unfortunately, after I deleted the application, the App Store still thought that it was installed and wouldn’t let me download another copy. With the aid of a great little application called Find Any File , I removed every trace of BBEdit from the machine, including all preference files and application support files.
The App Store was still convinced that it was installed.
Then, I began searching the internet, which revealed some frustrated App Store customers, who were mostly frustrated with their Xcode experience. The search didn’t help.
For some reason, I decided to go back to Launchpad and saw the BBEdit icon there. I clicked it and BBEdit started right up, though without my usual color scheme since I had deleted the application support folder. So, where was the file? On a whim, I disconnected my backup drive, opened the App Store, and BBEdit was finally gone with the option to install. I Pressed the install button, and BBEdit was automatically installed.
Lesson: Launchpad sees apps on external drives, so disconnect any external drives to install a deleted app to your main drive. Then, reinstalling should be the quick and easy process that it’s supposed to be.
