kao Posted April 29, 2015 Share Posted April 29, 2015 Buggy/non-working by default on Win7 x64. Reason - certain features require administrator rights, but EXE manifest doesn't say so. Link to comment Share on other sites More sharing options...
RDGMax Posted April 29, 2015 Author Share Posted April 29, 2015 Tested on windows xp, seven, 8 & 10 32 / 64 bits show any error? message? Link to comment Share on other sites More sharing options...
kao Posted April 29, 2015 Share Posted April 29, 2015 No error, just the 2nd process won't run, you get "bad boy" message right away. Right-click and "Run as administrator" solves the problem. Probably. At least it seems to run as intended. It might be as well that my antivirus (Bitdefender) doesn't like the dirty tricks you're using.

kao Posted April 30, 2015 Share Posted April 30, 2015 @RDGMax: thank you for kind words. It was actually not that different from previous one. All the main protections (anti-patch, anti-debug, encrypted strings, hidden good boy message, etc.) are the same as before. The biggest change was that you added an extra check (probably because of my tutorial ): if (Strings.Len(correctSerial) == Strings.Len(enteredSerial)) // this check is new in v5{ if (Operators.CompareString(correctSerial, enteredSerial, false) == 0) { goodBoy(); }}So, instead of logging CompareString parameters, I logged Strings.Len parameters. Easy as pie. 1 Link to comment Share on other sites More sharing options...
