I installed  MCR （R2012a (7.17) 64-bit），but I can't run DKE. Using DKEGUI.exe, I get message:

idx_gradients{1} = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18];
idx_gradients{2} = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18];
idx_gradients{3} = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18];

command line: dke DKEParameters.dat
An Error has occurred while trying to initialize the MCR.
The error is: Fatal error loading library C:\WINDOWS\system\libmx.dll Error: The specified module could not be found
Error:mclmcr initialization failed


I don't know if I installed MCR correctly. When I installed MCR, I just selected installation path,should I select a specific path? 

I tried to set environment variables,but it still didn't work(message above).I really need help.
