I don't get it why ther's the char array's length added to the minute in your solution @ stlcoder, can someone explain that to me? All i can see is machinename + machinename[0] + current minute + clipboard text

A simple thing to do is to clear the clipboard contents before entering the serial into the keygenme.

1. Empty the clipboard.
2. Get machine name
3. Get current minute
4. Translate the first character of the computer name into ASCII corespondent
5. Concatenate comp. name+ascii of the first char of the comp. name+minute
6. Input manual the result into the keygen
7. If the minute has changed the serial is changed too

Used reflector + reflexil to print variable with pass instead of "Wrong pass, try again".

Used JustDecompile and had it print "name".. realized it was using clipboard as part of pass, copied a single a, ran my "Keygen" and typed in the password.

To get the pass:
Used Telerik JustDecompile (trial version) with the Reflexil plugin (automatic install/download/ from within the app) to open the assembly. I also had to choose to load assemblies from the menu to give me access to System.Windows.Forms.MessageBox. I used the instruction editor ( to add a simple call to MessageBox right after the "name" variable was loaded onto the stack but before the "0" used in the Compare() operation was loaded. A MessageBox displayed showing me the password.

To crack:
Reloaded the original executable and in the same function used the instruction editor to update the (50)NOP to (44)NOP and changed the string in that message box.

Use Reflexi go to instruction 47 of Button1_Click
Edit ldnull into ldloc.0
Then we will see the key in the messagebox title
