Max 2017 refuse to open after install of FumeFX 4.1

[Michael Plaengsken]

Hi
After installing Fume 4.1 for 3dsmax 2017 max won't open anymore, giving the an error massage:

DLL failed to initialize properly - not loading.

Max will not start anymore. Even uninstalling Fume didn't help. Had to reset windows to an earlier system restore point! any ideas?

thanks
Michael
