app not installed after it corrupted in the first place.

[Android Central Question]

So,I download FL studio 3 mobile from a third party website.It all went well running smoothly.But one day i used my phone until the battery died and when i charged it and switch on the phone.The fl studio mobile 3 app logo is turned into android logo and it says the app is not installed on your phone.I deleted it and downloaded again from third party websit again but this time it says 'app not installed'.So,i think it is because the previous app is not completely gone from my mobile phone so thats why i can't install it.

Welcome to Android Central! What 3rd party website did you install from? Is there a reason why you can't install it from the Play Store?
