Programs kills itself - how to avoid that?

[aldente]

Hello!

There is a software NAT router (http://www.nat32.com/download/nat32e.zip) which demo-version is limited by a maximum runtime of one hour. After that, the program terminates itself.

I played around in WDASM and searched for all calls to Kernel32.ExitProcess, but that was no real help. There is also a call to SetTimer, but I had no success with that either.

The programs kills itself after one hour - manipulating the system clock does not help.

Are there any other ways to delay an action for one hour? How does a program end itself (is there anything I can have a look for)?


Or maybe even someone of you may have a look at NAT32 directly...
