Patching file

[Notmex]

Why dont you guys try to use a DLL with a Vectored Exception handler? This would not modify the code or trigger any CRC mechanism. You could use hardware breakpoints or PAGE flags to catch the exceptions and work your modifications out from there.

Hi Notmex-

Can you explain what a Vectored Exception handler is or point me in the direction of a good tut? I'm working on a few FlexLM (11.9 - 11.13) targets and I want to learn as much as possible.

Thanks!

Hi Peterg-

Any updates? Have you been successful or made progress? I'm having the same issue at the moment.....

I'm assuming some progress was made by someone, as there is a file floating around for the specific protection he is referring to patched to pass checksum from what I gather. Haven't really looked into it other than what I've seen on the boards, as I have no need and am licensed for work anyway. This may be the original file he was referencing
