Firstly, start with a clean Windows Server 2008 R2 build or remove the existing Microsoft Dynamics CRM installation.
I had to perform the following additional tasks to get past several environment verification checks:
- Repair the Microsoft .NET Framework 4 (Net.TCP Port Sharing Service errors)
- Delete existing Microsoft Dynamics CRM Databases
- Use Network Service security account for Microsoft Dynamics CRM services (optional)
- Don't specify Email Router settings
