To add a solution to a possible common problem others may be having following this guide:
When installing EasyTuTu, you may experience the setup.exe hanging.
There's 2 reported solutions for this that I found here
- Killing the process rundll32 in Task Monitor
- Enabling Compatibility mode with Windows XP SP2 for the following files: _ISDel.exe, setup.exe & TutuCore.exe
I personally used the 1st solution which worked instantly.
