Change to

004D6423 |. 0F84 7C000000 JE SysMech4.004D64A5
I tested it and found no bug.

I tried inline Patching ASPACK'd System Mechanic but it will not allow me to copy the changes to executable. Can u guys tell me why? Temporary injection of my own code and running in Olly, the software will run registered killing all nags. But it will not allow to make changes permanent.

This is how i inject my code and it works. The app runs registered
00C704FE 68 E4666900 PUSH SysMech4.006966E4 (Signature bytes)

006966E4 C605 25644D00 >MOV BYTE PTR DS:[4D6425],7C
006966EB 68 C4666900 PUSH 006966C4 ( Real OEP)
006966F0 C3 RETN

Now if i try to make the changes permanent it will tell me that the data not found in the executable and will disable the "Copy" & "Copy All" button.
I'm using Olly v1.10 Step 2
How can i do it in Olly if i don't want to use Hiew
Someone plz explain
Regards,
