Acquia installation is up-to-date but requests update and reports errors
For the errors, I think you could continue developing your Drupal site with it but for me I wouldn't like those in my site. I myself don't know the cause of it thought but I found a recent issue in the Acquia forum: Errors on Clean Acquia Drupal Install which still has no reply on a fix.

Option 1: Use Acquia

Try uninstalling and reinstalling the whole Acquia Dev software and see if the issue still persists.

Option 2: Use XAMPP(I use)/WAMPP

I've been using this since I started web and its straight forward. You don't need to change any settings too. What you need to do is:


Download the .exe from the XAMPP page
Install the application
Download Drupal Core that can be downloaded here
Extract Drupal Core into C:/xampp/htdocs/[your drupal root folder] (if you just chose the default settings of XAMPP on installation)
Go to http://localhost/phpmyadmin and create your database there, just use the defaults too
Start the installation of your Drupal site by going to http://localhost/your-drupal-root-folder-name]
