Corel USER to USER Web Board

Hi Folks,
I've been trying to Install Aftershotpro3.
The installer downloads OK, it's about 640kB but when I run it all I get is the screen shown in this screenshot.
I've tried running as administrator, no difference and I've scanned my registry for conflicts.
My system is a Dell XPS 410 with 500Gb Samsung SSD and 8GB of RAM plus an ASUS R5 230 graphics card.
Processor is a Core2Duo 2.4GHz and I'm running Windows 10 64 bit.
Any suggestions or info gratefully received.
Thx.

I've just downloaded and installed to my DELL laptop fine with no issues.

Try disabling your antivirus in case this is having some adverse effect on the installer.
