I can't get this engine to run on my i5.
I use Windows 7 Home Premium.

I get the following:

Anybody else have success with Fizbo?

It seems to need a modern CPU to work. It works on my Intel Sandybridge laptop, but not on my AMD Phenom II X6.

Maybe it needs AVX support, first introduced by Intel with Sandbybridge, and first supported by AMD with Bulldozer.

2800 and original. Great!

Some comparison with Crafty, GNU Chess and Scorpio seems indicated (only open source WB engines in that region).

"requires "popcount" and "bitscanforward" instructions" --- see Graham's original post.

Yes, and the machines above have that support.

You're right---must be something else.

Seriously, Windows must produce a crash log, or give some information about why/how the program fails, right? Maybe run it from a command line, under a debugger?

Well, it works on Intel Sandybridge, so presumably it must be something supported on those and later CPUs that isn't supported on earlier processors.
