Difficulty using MCStreamMEX64.dll with Matlab 8.1 (2013a) on Windows 8 OS

Hi All!

I am trying to use my own code to open .mcd files in Matlab 8.1 (2013a) on a 64-bit Windows 8 system. I have been using the datastrm.m file provided with MC Rack and run into something I am not sure how to solve.. I have tried using MCStreamMEX.dll and MCStreamMEX64.dll (i.e. making sure they are in the registry and on the path for Matlab) and using both returns the same error..

********* Undefined function 'MCStreamMEX' for input arguments of type 'struct'.

Error in datastrm (line 286) retStruct=MCStreamMEX(tmp);

Error in analysis (line 95) D = datastrm(file_name); % gets data from .mcd file ********* Undefined function 'MCStreamMEX64' for input arguments of type 'struct'.

Error in datastrm (line 286) retStruct=MCStreamMEX64(tmp);

Error in analysis (line 95) D = datastrm(file_name); % gets data from .mcd file *********

Following a comment posted by Jens (RE: MCStreamMEX.dll for 64 bit computer) I have tried to register the two .dll via command prompt using: regsvr32 "Path filename" and Windows returns the following error: "The module "C:\Program Files (x86)\Multi Channel Systems\MC_Rack\MCStream...\MCStreamMEX64.dll" may not be compatible with the version of Windows that you're running. Check if the module is compatible with an x86 (32-bit) or x64 (64-bit) version of regsvr32.exe"

I am already beyond what I know about computers at this point.. hoping this makes sense to someone! :-)

Many thanks in advance!!
