Ah, I didn't know about PEiD or ProtectionID. I do however have OllyDbg, which I sort of know how to use a little.

Edit: If I understand what PEiD 0.95 is telling me, RAR Password Unlocker 4.3 doesn't have any protection.

Are you trying to crack the software ???....Or trying to activate with a patch crack or serials ????

If it's the later .......First rule ......

Disconnect from the net before you start
Install the software
Apply patch crack or serials
Then make sure the software can not phone home (block with firewall or turn off updates in settings)
Reconnect to the net and enjoy

Trying to crack it myself.

Let us know where you had with this
by the way, I hope you master Assembly
