Installation and running problems

Hello everybody,
I am having a hard time trying to start my invest-experience,
I have installed the latest version on Invest (3.7.0) on a windows10 system.
Installation works without problems but whatever is the model I try to run the system lounches for a few seconds a prompt-like black windows and the program closes automatically.
If I try to run invest.exe from dos prompt I have this following list of outputs

Traceback (most recent call last):

Hi @paolo.vassallo, thanks for posting your issue.

I found some relevant info about the error here: https://stackoverflow.com/questions/35176270/python-2-7-lookuperror-unknown-encoding-cp65001

And it makes me think that our latest development build of InVEST might resolve this, since it is built with Python 3. Would you mind trying it out? http://releases.naturalcapitalproject.org/invest/3.7.0.post839+h89ab3f9d1349/InVEST_3.7.0.post839+h89ab3f9d1349_x86_Setup.exe

I am very interested to see if this is resolved by the dev build @dave linked! Encodings tend to be quite a gnarly issue.

Dear Dave,
it seems that this has solved the problem I had. The program now load the graphical interface and I am planning to run a few simulations in the next few days.
Thank you very much for your timely and effective help
All the best
Paolo
