Can't Mount .iso File on Windows 8

[tribute25]

I have an 8.8gb .iso file that needs mounting but all I get is an error message when I try to. I've tried Power ISO but the file is far greater than the free 300mb limit. Any ideas? Thanks

You could try daemon tools (http://www.disk-tools.com/download/daemon). Are you sure the iso file isn't broken?
