Hia,
I am working on a target called Tapeview and have run into some trouble. Some general info:
- The "real" version is protected by a dongle of some kind along with a key.
- There is a trial version that one can download that expires after 14 days.
- There are three versions of the program. Bronze, silver and gold.
- One can receive extended demo keys that make it gold/30 day. This leads me to believe that the demo is the full version, and can be cracked without key/dongle.
- It complains when setting date back.
- The demo version needs a password for the setup.
- The setup program used is some thing called innosetup.
- It is MS VC++
So what I have done so far is I have cracked the setup password so the application installs ok. However cracking the application seems harder. When browsing through the code with ollydebug I saw several references to "debugger detection" etc. but they never seemed to trigger on OllyDbg. However when trying to breakpoint on the usual functions for serial fishing I get nothing. I am able to break on createfilea during start-up but I haven't found anythign interesting yet (ongoing). So if anyone here could give me some hints as to how to proceed I would appreciate it. I am not asking for a complete answer... just some hints. I will post when I find something intersting. Thanks.
