The software that I use was protected by FlexNet version 11.13 and pattern 4C894C24204489442418488954241048894C24084881EC78010000488B05 ( pattern6_addr+20: pattern6_addr+20+3 ==> 4881EC>33C0C3) was working. Now the software moved to FlexNet version 11.16 and I couldn't find a working pattern so far. I will be so grateful if anyone can help me on this?
I was able to patch vendor daemon .exe file. Vendor daemon is up and running without an issue.
I did the same patch on client side .dll file but I'm still getting "license unavailable" error.
Patching process is like this;
"look for the string "SIGN%s=", two of them is found, and inside the same function; find the call statement at the end of the function and modify the call statement to "mov eax, 1"
It looks like there is another protection on client side .dll file. Does anyone have an idea about it?
License server is up and running without an issue. When I start the client software, I get "Invalid (inconsistent) license key. (-8,523)" error.
I tried with different encryption strength on the license (113BIT, 163BIT or 239BIT) but still getting the same error. (lmcrypt is created with 11.4 SDK)
I really need a guidance from the experts what to do next.

locate l_pubkey_verify and patch it also for client part.
BfoX,
I searched for "2930h" (BA 30 29 00 00) and in the same sub I modified the last call from "call __security_check_cookie" to "xor eax, eax nop". When I start the client software, now I get error "Error in Public key package.(-115,10544)". Am I patching the wrong place for l_pubkey_verify?
