Attention, the common error for Windows 64Bit owners is to launch the 64Bit version of SLIMax Manager!
No, if you follow the instructions in first post the old Papyrus API is NOT available in 64Bit so only the 32Bit version of the plugin has been done.
The 32Bit version of SLIMax Mgr is inside the
C:\SLIMax Manager\
I suggest to make a shortcut on your desktop. Also, the API is capricious, SLIMax Mgr must be ready BEFORE launching the NR2003 simulation.
Personally, it was a lot of fun to play again this sim with my rig!
Have fun!
