Ladybug / Failed to remove downloaded zip file

Dear community,
I am trying to install the new version of Ladybug 1.1 but it just sends errors.
Any tips about how to solve it?
Thanks a lot for your help.

Here is the text:

Ladybug Tools installation folder created at:
C:\Users\niko_\ladybug_tools

Failed to remove downloaded zip file: C:\Users\niko_\ladybug_tools\python.zip.
Next you should:

  1. Run the installer component below.
  2. Run the set_python_path.bat file WITH RHINO CLOSED that will appear in: C:\Users\niko_\ladybug_tools

Optional installation steps include:

  1. Install OpenStudio.
  2. Install Radiance.
