  1. Solution exception:An URBANopt installation was found at C:\URBANopt-cli-0.14.0
    but the URBANopt executable is not accessible.
    Der Befehl “uo” ist entweder falsch geschrieben oder
    konnte nicht gefunden werden.

As the message suggests, it seems you need your IT to greenlight the URBANopt executables or turn off something in your antivirus software that is blocking the URBANopt executable from running.

Thank you but it didn t work, I am still getting the same message…

Hello, I also encountered the following error when running DF URBANopt:

  1. Solution exception: An URBANopt installation was found at C:\URBANopt-cli-0.14.0, but the URBANopt executable is not accessible. ‘uo’ is not recognized as an internal or external command, operable program or batch file.
    While the OSM module produces simulation results, it doesn’t support multi-core parallel computing like URBANopt.

The same error also occurs with the template file.

Yeah I tried so much already…
Could you find a way to solve it?

Hello, my friend~ I haven’t got it working yet. I’m using the OSM+OSW modules for batch simulation of group buildings, as Urbanopt and its other features are still unavailable.

Hi, I also tried with OSM+OSW but the results are “empty”, I don t know what I am doing wrong… did you manage to do your simulations?

The full error message reads

Blockquote
Failed to create folder:
The value cannot be an empty string. (Parameter ‘path’)
Runtime error (IOException): Access to the path ‘C:\Program Files\Rhino 8\System.check_uo_version.bat’ is denied.

I was wondering if the issue is the . before the check_uo_version.bat filename, but then I also wondered why on earth it would be checking in a Rhino system file directory, so I am left wondering whether the call assert os.path.isfile(_epw_file), in the script is looking in the wrong place? Is looking up the Operating System path the right lace to look?

No solution as yet, except to note that the most recent downloadable version of urbanopt is version 1, which is almost twice the size of version 0.14
