it won't load under Fritz and won't work under ChessGUI here. I wonder if it's just me.
64-bit version does not load over here. I was able to get it to load with 200 MB hash just once however.
UPDATE: Problem seems to be hashsize related. I can load it with a 200 MB hashsize.
I can run it with 96 MB main hash + 16 MB pawn hash. However, increasing pawn hash to 32 MB causes a crash.
And, it seems to me that the allocated hash size is half of the set one.
It allocates main hash by the power of two. It means you can set it to 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, etc.. If you didn't allocate it correctly it rounded off to the lower value with power of 2. When you set it to 96Mb, it will use 64 Mb.
About the pawn hash size, it is not in Mb but power of 2 already. So 16 = 1Mb, 17 = 2Mb, 18= 4Mb, 19 = 8Mb, 20 = 16Mb, 21 = 32 Mb, When you set it to 32 it will use 128Gb of RAM, since it can't allocate it, the engine will quit.
