Does anyone know why the "install" button on my Droid4 might not responding when I try to install this?
I had the app before, removed it, but have missed it, so I want it back. I think it's more accurate with the current temp reading than my weather pro app (more about predictions, I believe).
I have tried several apk installer apps. Some lead to this dialog box that wants me to choose an app to open it, and the apk installer app is not listed in it. But with Root Explorer I can click the apk file which gives me the dialog "this is a package installer, what action would you like to perform?" and I click install. It lands me in the right window, however, the "install" button does not respond, only the "cancel" button works.

In my settings under applications, the "unknown sources" box has been checked to allow installation.
I have not tried installing any other apps, so I am not sure to which extent I have this problem.
Any suggestions are greatly appreciated.
