Tried again, but getting-

I can't seem to find 4.5.3. I'm pretty sure that was the last version I had. It's not listed in the old os page 
Or is 4.5.2.07 the last one ??
I have emailed support. Thank you.
4.5.3 is in "release versions"

I got this exact same thing with WIN7 x64 and my system.
First install of 64 bit version gave me BSOD
Second and subsequent installations gave the same popup as Sibanger saw.
Tried to uninstall manually, but the installer is missing from "Programs"
As a workaround, I will re-install 4.5.3
Is there a solution for it yet or will this take a new build?
4.5.3 is in "release versions"

Thanks Marc.... 
For some weird reason, it was not showing in my browser. Fixed.
Cheers
