Fusion beta 3 installer error

Hi,
I just installed the new Fusion beta 3 and I wanted to install it in a directory of my choosing - like the installer says I can - but as you can see in attached screenshot there IS no 'advanced' option to select and modify the installation. So beta 3 overwrote beta 2 without giving me an opportunity to change this.
Please fix this so we can get some control back over our installations.
