The vital trick for using Windbg is how to navigate to your destination. It can perform both kernel and user mode debugging it has friendly GUI and standard shortcut keys most importantly, it can handle large binaries. Fortunately we found one, and that is WinDbg. SoftICE should work, but its mouse problem makes me reluctant to use unless there is no alternatives. Visual Studio’s integrated debugger seems can only work with code built by VS (I tried “Debug Processes…” but it failed). It’s impossible to debug it within W32Dasm or OllyDbg (W32Dasm has trouble just loading it).
Moderate executable, ansys.exe is huge – 50.1 MB in size. Gauss 4.0 has a CRO license – the only one I have ever seen so far.

Unlike IMSL CNL or other software that has a 1 It turns out to be not so, there are very big hurdles waiting for us. Preliminary Attempts With the experience of, I thought it would be an easy job at first.

ANSYS has numerous features – more than any other software I’m aware of – total of 223 in original license. So the target in this article is ANSYS 8.0. This is really an annoyance and I decide to get rid of it (I could configure ZoneAlarm to let lmgrd/ansyslmd pass every time but I don’t want to do that). The C/S communication is on IP/ports/sockets and it causes my firewall ZoneAlarm Pro 3.7 to pop up window asking whether to allow such connection. Since it’s counted license, FLEXlm server lmgrd.exe and vendor daemon ansyslmd.exe must be started prior to each run in order to serve the application request for license checkout. At this moment we are not actively using PGI or HyperWorks, but we do use ANSYS regularly. Licenses of the first two are permanent but counted without HOSTID=ANY, the last one is not even permanent.
Among software on my hand there are three of them: PGI C++/Fortran Compiler 5.1, Altair HyperWorks 5.0, and ANSYS 8.0. What interest us here, however, are the ones that employ FLEXlm but don’t have “permanent uncounted HOSTID=ANY” license. Examples include Mathematica, SAS, SPSS, SolidEdge, Matlab, Femlab, MathCAD, Lindo, Origin, Labview, Tecplot.

A lot of software also use their own schemes such as serial number and password, and cracking against them ranges from keygen to patching. There are many – Intel C++/Fortran Compiler 8.0, Intel MKL 5.2, Fluent 6.0, Maple 7.0, Gauss 4.01 – these all have “permanent uncounted HOSTID=ANY” type licenses. Problem Description After successfully reverse engineered the protection of IMSL CNL 5.5, our attention moves to other FLEXlm guarded software. Readers are encouraged to consult before continuing if they have not done so.
