Using executable from anaconda constructor, activating environment

Question

I am trying to get some python software to a windows machine with no access to internet. To do this, I made an executable of software needed in anaconda using constructor. It installs fine, but when I try to run python it says that the environment has to be activated. But when I tried to install anaconda for that environment and make an executable, constructor refused saying that there were conflicts. Conda was installed on it's own.

Steps taken:

conda install opencv tensorflow-gpu keras spyder pandas

Create an environment.yaml file; defaults did not work, used these channels instead:

http://repo.anaconda.com/pkgs/main
http://repo.continuum.io/pkgs/free
http://conda.anaconda.org/anaconda
https://conda.anaconda.org/conda-forge

conda list -e > req.txt
(This gives me the list of packages for construct.yaml)

constructor [directory-with-construct.yaml]

Trying to activate an environment after installation, it tells me to initialize the shell.

Trying to do that with:

/directory/_conda.exe init cmd.exe

Gives

Warning: Cannot install xonsh wrapper without a python interpreter in prefix: [some-local-directory]
needs sudo ... (but this is windows!)

So either, how do I get anaconda on an environment to work with constructor; or, how do I activate an environment in conda after installation?
