I don't really get the difference between 2.0 and 1.1.
the registers aren't even showing up as 64bit format in 2.0.
Also 32bit apps take way too long to process with.
Plugins aren't even fully supported.
Is it possible to debug 64bit apps in 1.1 managing the problems
that I listed above?
I'm using 64bit Windows 8.1 and I;m trying to debug a 64bit sample file.
OllyDbg currently does not support debugging 64 bit apps, however the developer stated to start the development of a 64 bit version as soon as his free times allows him. For a 64 bit debugger, take a look at WinDBG.
Update 2021: These days, x64dbg is also an excellent choice. Its design is strongly inspired by OllyDbg.
