I have been asking this question for a week with no  answer.I`ll try to make it simple.
1.This is about those who have Win 8 pro 64bit and Sonar X3 64bit.
,the others cant help me Thanks anyway.
 
Look in the folder Program files/cakewalk/shared surfaces/ and tell me if the MMC.dll is there.
MMC.dll not MMC help file.
Dont look in  Program files (x86)/cakewalk/shared surfaces that`s the 32bit folder and I know it`s there.
Thanks in advance
Peace

I find ONLY the help file. There is no MMC.dll in the folder.

Well that`s the answer at last.Cakewalk need to fix this.
I wonder if MMC.dll 64bit exists at all,maybe I can download it and try to install it myself.
Any body knows of a work around for this?How can I use the 32bitdll on sonar 64bit,copying it to the 64bit folder does not work I tried that already.
Peace

I don't think it does. If its for MIDI Machine Control it may not be needed as a DLL. I think one would use the Generic Controller.  

"I don't think it does. If its for MIDI Machine Control it may not be needed as a DLL. I think one would use the Generic Controller.  "
Then how come it is in the 32bit folder and works perfect (for transport only) with my Yamaha 01v96i?
Peace

If you knew that why ask? 

Sorry John I ask because I need it in the 64bit version,I`m trying to figure out if this is a bug or something wrong in my setup.
Normally in this forum I solve all the problems but I think this time Cakewalk has to help me.
Thanks for trying to help
Peace

I made some reserch and this problem looks very old.
