I\'ve recently installed Anaconda (using the default settings) on Windows 7. When I try to open a .py file by double-clicking it, I get the Open with...
option.
You must create a spyder.bat file with the following content:
start C:\path\to\Anaconda3\pythonw C:\path\to\Anaconda3\Scripts\spyder-script.py %1
Remember set the path where Anaconda is installed.
Then, use the Open with...
dialog and select your new spyder.bat batch file.
It works on Windows 10 Home. I hope it works in Windows 7 too.
