You don't know what you're talking about, do you? The .zip file contain Electrum source code, not .exe/.msi installer
It's actually an installer for windows OS but to be able to install it you need a python installed in your PC.
I would like to add the method here if he wants to run the wallet in python.
He should need to install the
python for windows
Then after installation, open command prompt then run this command line below.
Now install the python electrum installer command line below.
pip install https://download.electrum.org/3.3.7/Electrum-3.3.7.zip
After installation, you can use this command below to run electrum.
Make sure you downloaded and extracted Electrum-3.3.7.zip then open the folder of the extracted file the run_electrum file should be there and open command prompt under this folder and run the code above.
Or you can use this command as sample location folder.
python C:\Electrum-3.3.7\Electrum-3.3.7\run_electrum
