Edit example1 but "Create Process Failed"

I am new to the dynare . As a test, I was trying to edit the example1 file. It gave me an error message saying that CreaProcess Failed" , “Cannot create Child Process”. Any help please , thanks a lot !

Please provide more information. Which operating system are you using?

Window 7

Did you try reinstalling Dynare?

I downloaded a lower version of Octave and that particular error disappeared ; However, it gaves me another error message saying that a calling function could not find a mex file (as in the libary or depednents)

That indicates a problem with your installation of the mex-files during the installation process. Try a full installation. Also, which Matlab are you running? Is your system 64 or 32bit?

Thanks, I don’t have Matlab running. My system is 64. What do you mean by full installation?

Are you using Octave? Which version?

HI, I am also a new user of dynare and facing the same problem as mpeng in trying to run the examples provided by dynare.

I am using Octave 3.8.1 (MinGW) for Window 7 with 64 bit, and the dynare version i am using is dynare 4.4.2.

The octave system returns following statement when i type in command “dynare example1”.

Configuring Dynare …

I check that the mjdgges.mex file exists in the location \mex\octave folder.
And when i adopt the 3.6.4 version of octave to run this command, this problem is gone.

Thank you for your help.


The binary for Dynare 4.4.2 is only compatible with Octave 3.6.1, not 3.8.1. You can download the right version of Octave on the Dynare website.

The upcoming Dynare 4.4.3 release will be compatible with Octave 3.8.1.


Dear All,

I had the same problem with Octave/Dynare but now with Dynare 4.4.3 and Octave 3.8.1 (from Dynare website not Octave!) everything works like a charm:)

Don’t forget to run in Octave command window
addpath c:\dynare\4.4.3\matlab

Thank you all for help!
