Dynare could not open mod files and warned preprocessing failed

hi ,sir:
i use matlab 2016a and dynare 4.4.3, but when i try to run example1.mod after installing my dynare, it got an error like this:

i do not understand this mean, i need you help.

Have a look at the folder on the left. You are not in the examples folder where the mod-files are but one level above that.

thanks a lot, i will try it again.
