Converting Fuzzy system to Java package using Matlab builder JA in 64 bit windows 7

Hi

I have converted one fuzzy system into java package using Matlab builder JA in 32 bit windows 7 operating system and it is working fine. When I do the same coversion in 64 bit windows 7 operating system I am getting the following error during build process.

:
:
No conflicting MATLAB file found.

Any help would highly be appreciated.

Note that .mat file and .fis file that I have created in 32 bit and it is working in 64 bit Matlab (before conversion) but got error in build process for conversion from Matlab to Java package.
