I’m using Matlab 2022b and the dynare5.2. When I execute the example1.mod file, it’s not working. And it showed me that "dynare (line 281) evalin (‘base’, [fname ‘.driver’]. I have find many ways but it still can’t be solved. I really need some help to solve it. ---

What is the full error message? ---

That is strange. Does you full file path include any non-standard characters that may throw off Matlab? ---

Sorry, I don’t quite understand what you mean. I add the Matlab file of Dynare to Matlab. The file path was copied. So I think it’s correct. ---

I meant the full path. In my case it would be ```auto C:\dynare\5.2\examples\example1.mod ``` ---

I just ran `example1.mod` on my system without any problem. I am using `MATLAB 2022a` with `Dynare 5.2`. My path is > C:\dynare\5.2\examples ---

Can you go to the `Dynare` folder on `C drive` where you installed it and find the `examples` folder? Inside you will have `example1.mod`. Can you navigate to that folder from your `MATLAB` (set that as your current `MATLAB` folder) and then try running the file? ---

In the `+example1`-subfolder, is there a file called `driver`? ---

I just run the example1.mod, but it still doesn’t work. The error is “The use of operators is invalid.” ![image](https://forum.dynare.org/uploads/default/original/2X/e/e54137a5c8c13578071f2acdc253b1e35402feb1.png) ---

How did you try to run it? It seems you tried to execute it as Matlab code. ---

I try to run it by using “dynare example1.mod”, but get the error "（The name could not be resolved） ‘example1.driver’。 error dynare (line 281) evalin(‘base’,[fname ‘.driver’]);" ---

Did you try running the file by typing in `MATLAB Command Window` the following statement? `dynare example1` If this doesn’t work, maybe deleting the `example1.driver` file and then trying to run `example1.mod` might help. ---

I have worked out this problem! I share my resolution： I created a working folder, works, outside of the matlab directory to place the mod files. Then in matlab > > cd:\soft\ works > > dynare bkk > > succeeded!
