Hi Bertho,
A couple of things that may help...
The stand-alone LazyCam 3.00 (Pro when licensed) installer is farther down on the downloads page, after Mach1,2 and Quantum.
Once installed, you need to place a copy of your "LazyLic.dat" file in the LCam folder.
Also... Note: This version requires the ".net 2.0 update" from Microsoft. Otherwise you will get an error at startup.
