An error occurred: "application not installed"

[JoseRichmond]

Greetings, A notification that reads "application not installed" displays when you click the icon. In order to start it, I had to go to Google Play. I would be very grateful for any advice on how to fix this problem.

Thank you very much!

Have you installed the app itself? It should show in your Android Settings > Apps. If not, reboot, check you are signed in with the Google account you used to purchase the app, then download it from the Play store.

Also make sure you have an internet connection after installing or if you are opening it for a few days in case the Play store needs to check.

You might find other information with a search for your specific error message.

After the latest update, I had a similar issue. I was getting "Application Not Installed, Please purchase" or something similar.
When I went to the app on Google Play, it didn't ask me to purchase but would open the app. It's over a week since this happened so I can't remember precisely the sequence of events.
Now, however, I can't use iRealPro unless I am signed into Google on my device. I do not wish to be permanently signed in to Google and didn't have be with previous versions.
Is there a way to download the previous version of iRealPro?? (ie go back to where I was a week ago).
