    API Parameter Help

    What is needed in order to make the Api Parameter Help work in OllyDbg? I'm referring to the "comments" that appear in the right column whenever a Windows Api is called, where Olly shows a friendly display of the function arguments to a call.

    I'm new to Olly so I could just be doing something wrong, but this information isn't showing up for me at all. I'm using Win7 x64, if it makes a difference. The problem exhibits on both Olly 1.10 and 2.0
    I promise that I have read the FAQ and tried to use the Search to answer my question.

    - Modify item API help file=[path]\WIN32.HLP in ollydbg.ini
    - On API CTRL+F1

    Hi, thanks for your response.

    I actually know about this, unfortunately my problem is slightly different. I'm referring to the comments that show in the right hand column of the main disassembly window, that show you live parameter values for each of the parameters based on the calling convention / value of items on the stack. For example, if I call CreateFileA(LPCSTR, DWORD, DWORD, LPSECURITY_ATTRIBUTES, DWORD, DWORD, HANDLE), then on the right hand side it would say something like:

    hTemplateFile = NULL
    dwFlagsAndAttributes = 0
    dwCreationDisposition = OPEN_EXISTING
    etc...

    After some more investigation, I think maybe the problem is that it just doesn't work under Wow32, since I was debugging a 32 bit app on Win64. So I'm building a new VM with 32-bit OS to see if that fixes the problem.
    I promise that I have read the FAQ and tried to use the Search to answer my question.
