Hi Jorge,

Welcome to MSDN forum.

According to this error message, you may refer to the blog below, which says that Visual Studio is not able to delete the application data in your local packages folder, then you could just delete that. C:\Users\<UserName>\AppData\Local\Packages\ folder.

https://blogs.msdn.microsoft.com/paraswadehra/2012/12/08/error-dep0700-registration-of-the-app-failed-an-internal-error-occurred/

And the blog gives the reasons and how it works.

Best regards,

Fletch
