Right if you don't have a standalone installer that could be problematic. I have a place you can easily drop it but probably not worth the effort based on that.

Confirming you're trying to install this one?

What about trying this?

Note there's some potential for malware and the like here. So make sure virus scanner is running although no reports there. Looks like there might be the odd problem installing but worth giving a go. Seems turn off your internet connection (unplug Ethernet or turn off Wifi) whilst installing.

I'm getting it now, but it's coming down fairly slowly (50 kByte/sec)
