The Wolves of Steel Installer shuts down without warning.

[BIGD101]

Hi guys. I'm following the steps for installing the:

The Wolves of Steel 2.2_SH5 Expansion Pack_v2.2.9_Full

I've got up to starting the installer, if I leave it without pushing install it just shuts down without warning. I've i'm fast enough I can get to the next page and paste in the directory. It starts to install and after about 5 seconds on installing files it does the same thing, just shuts down without warning.

Anyone else had this issue? I've turned off all my protections etc. Running Windows 10.

Any help would be much appreciated.

Cheers
Duncan
