The problem is somehow in ArchiCAD installation.

I had AC12 with Maxwell addon working ok (Fujitsu Celsius H240, Vista 32 bit, Dual Core, Avira antivirus). This AC12 was installed from original DVD and updated gradually as hotfixes have appeared.

I installed AC12 to my new computer (Fujitsu Celsius H270, Vista 64 bit, Quad Extreme, Norton antivirus) from original DVD and updated it. Then I installed Maxwell plugin. It was not working. I copied plugin file from first computer, didn't help. I installed AC12 with two different country and older and original (DVD) build versions, didn't help. However, when I copied AC-executable and DLL:s from first computer and executed AC12 (build 2523) - plugin started working on second computer, too. So it seems that files installer creates are different on 64-bit system.

(Something else: after latest hotfix for AC12-FIN, Graphisoft's own MEP-extension has become deprecated, too.)

I've also have problems with my maxwell plugins. I have now a quad core. Have talking too nextlimit and there is a DevIL.dll that should be both under \graphisoft\archicad 12 and \windows\system32 path.

But it won't help me but have helped other.

*gaaaaaaaaah* Why does it worked on this machine before my harddrive crashed but not anymore? Everything else is the same.

Next limit have solved my issue, there was 2 windows .dll files that I missed in my /system32 directory.

msvcp71.dll
msvcr71.dll
