My 64 bit processor prevents me from using OllyDbg effectively for it does not support 64 bit!

Can someone suggest a comprehensive 64 bit debugger similar to OllyDbg or the likes?

Many thanks.

do you want to debug 64 bit apps or 32 bit apps on an 64bit OS?

because i used the OllyDbg 2.01 alpha 4 for the latter (eg the crackmes here) and wasnt dissapointed

I would like to use crack both 32/64 bit apps on 64bit OS

Do I need a different tool to crack 32 bit apps and a different app to crack 64 bit apps?

Edit: By the way, does OllyDbg 2.01 alpha 4 support 64 bit OS? I am trying to do the crackme tuts that I found here, but OllyDbg shits itself when I use it.

There is no better debugger for 64 bit environments than Immunity debugger from Immunitysec.

It looks exactly like olly, except its made in masterclass python.
