Android Question Problems trying to update my app

[desof]

Hi I am trying to install and test my app on my phone and I'm getting this error

Application not installed
An existing package of the same name with a conflicting signature is already installed.

I clarify that I just installed on a new PC so it's all new provable missing me something ..

I help?

Are you using the same keystore as before?

You can manually uninstall the previous package and then it will work.
