Dear Members,

[ahnmaru78]

Hello, Members.

I am a newbie for Olly debugger.
Sometimes, i got the error message below when i try to debug a file with olly
debugger.

"Unable to start file"[the file name to be debugged.]"

Do you know why i got it?

Please, teach me why and don't beat me.
Thank you and Have a nice day

1. does the file start without Olly??

2. Multiple explanations: Olly does not debug 16 bit applications. If your "not start files" are old MZ 16 bit DOS or Windows) apps, Olly complains.

3. Perhaps the files have anti-debug devices??

Requirements, search (http://www.woodmann.com/forum/search.php), etc. You know the deal.

Hmm.. never seen that error, usually the soft burps a system error and exits.

We are reversers or not???
If you want an answer the most simplest way is to debug Ollydbg looking for the error message. It's pretty easy to find out where the error occours.
If you are a newbie you can learn something new otherwise take it as a relaxing exercise

I am also having this problem. I have tried many different .exe files, including Ollydbg itself.. .both versions 1.10 and 1.09 and I have yet to be able to open a single file. Every time I get the error saying "unable to start file .. "

Is there a way to fix this?

Jhudora: What is your OS?

I don't think Olly works in x64 environments.

[Jhudora]

I'm running XP. .. is there something similar to Olly for XP? =\

[naides]

Olly works fine in 32 bit windows XP. [I]f you do not have x64 windows then the problem is somewhere else. Do you have another computer?
Try there.
Try a virtual machine.
Think about file permissions, work as an Administrator

[Jhudora]

I log in as the owner so I think I have full permissions for accessing files.. I don't have another machine nor do I know how to run a virtual machine.. Any ideas what the error usually typifies?
