On Premis Gateway install error

Hi All, 

I'm trying to install the On Premis Gateway on a new Windows Server 2012 build, however GatewayInstall.exe just crashes constantly.

I  have so far :

1. Ran as adminsitrator 

2. Download Full install exe.

3. Added all relevent accounts as Admin

4. Check .net 3-4.6 are istalled

5. Moved files to temp folder with no security restrictions...

I cant get the installer past initial extaction and execution.
