You have to install the 32 bit version... not the 64 bit version. I think that is right?? Kex exporter worked for me when I installed that... I have 2013 64 bit, 2012 64 bit, and 2012 32 bit all installed at the same time.
Follow along closely.....Go to Computer/boot drive(usually [C])/Autodesk/Autodesk_3ds_Max_2012_English_Win_32-64bit. Now run the "Setup32.exe". Once installed uninstall the Max 64 bit version. Now associate the Kemax plugin as before. Done!
Don't mean to necro this thread, but um... yeah, wanted to thank you guys. I'm just getting started on this and the !@#1235 installer insisted on installing on the 64 bit installation by default.
My workaround was to run the installer, wait till it unpacked into the directory and quit and run the setup32.exe.
I think I've got the RF7 KEMax plug in working now - going to try my hands at a first model, but can I ask, would I wreck my current install if tried to install the 64 bit install in tandem i.e. I went back to the main directory of this program and ran that install as well?
Or maybe I should just get the latest version, edit the model on that, bring the max file back into 2012 to do the KEMax stuff, would that work?
Also, this post now is in an interesting place. I'm going to be trying my model in RF7 yet I found this thread in RF6.
What do you old hands here do about important info like this that spans several versions?
I only came across this thread after a google when I first got the error as the OP did, and I figured it had something to do with the program being 64 bit trying to run a 32 bit DLL (don't really know if it's possible, it may well be).
