Is Dynare 4.4.3 compatible with MATLAB R2012b

I installed Dynare 4.4.3 under MATLAB R2012b
then when I input “dynare fs2000.mod” into the command window
it tells me :warning: Function C:\dynare\4.4.3\matlab\missing\bsxfun\bsxfun.m
has the same name as a MATLAB builtin. We suggest you rename the
function to avoid a potential name conflict.

Error using fprintf
Invalid file identifier. Use fopen to generate a valid file

Error in dynare (line 168)
fprintf(fid, ‘%s’, result);

I want to know
Is Dynare 4.4.3 compatible with MATLAB R2012b

Yes, it is compatible with 4.4.3. The first message is a warning that results from you adding the Dynare matlab folder to the Matlab search path including all subfolders. If you remove all those subfolders and only add the matlab subfolder, this message will go away.
Regarding the error message, I have never seen it before. Is it possible, you executed Dynare in a folder where you do not have write-permission?
