I have the file "C:\WINDOWS\Vbox\Common\vboxt420en-us.vboxlm" So I'll guess that I'm dealing with one VBox protected application.

This thing is, it are experied and now I want to crack it, I have read some tutorials at krobar but i found them in no help, the "bpx ShowWindowA" don't work. I have done the CTRL+N trick in OllyDbg (i'm using that debugger) and coudnt find that import.

Any ideas on how it's possible to crack vbox in ollydbg ?

sorry for this post, it seems quite desperate.. and it is..

Hello Acid_Cool_178 !

Do you mean "expired" (=trial time over) in your title? If yes, you need to reset it again. This can be done by deleting the "ws*.???" file in your windows\system directory (* is a number and ??? is the extension I don't remember any more) and the "os*.???" (if present) file in your root directory, as well as the windows\VBox directory. You should also uninstall and reinstall the application.

I don't know how to work on VBox with OllyDBG, but there are some tutorials available for SoftICE and TRW. Two dealing with 4.3 (1 (http://www.woodmann.net/fravia/dezzy_vbx43tut.htm) + 2 (http://www.woodmann.net/fravia/tsehp_vbx43tut.htm)) and one dealing with 4.2 (1 (http://www.woodmann.net/fravia/vbox42.htm))

The first 4.3 tutorial is said to only work with 4.3, but I managed to handle 4.2 by modifying it a bit, but I don't remember how any more.

That was os######.bin and ws######.ocx in the previous versions. Dunno if it's still the same or enough for a trial time reset.

OllyDbg doesn't appear to be the right/best choice since you've got to deal with some encryption/decryption routines. I didn't notice any radical change in different versions of Vbox protection in the past. Read the tuts. That will give you the insight you need.

Good luck.
