I'm playing with magento 2 in Windows platform - clean install of IIS 7.5, MySQL 5.7.10 and php 5.6.16
Trying to install it using web interface, passing all steps, starting install process and after couple minutes progress just stopped with mysql error in logs -
Aborted connection 21 to db: 'magento' user: 'magento_test' host: 'localhost' (Got an error reading communication packets)
tried to fix it with increased read\write timeout, without any success.
What I'm missing?
There are a lot of problems can be happened if you install and configure manually. I suggest you disable IIS7 and use the full package like wamp or xamp to make sure it work well.
