If you don't have the key just do: def find_vcvarsall(version): (HKEY_USERS, HKEY_CURRENT_USERS, HKEY_LOCAL_MACHINE or HKEY_CLASSES_ROOT)\Software\Wow6432Node\Microsoft\VisualStudio\version\Setup\VC If you already have the vcvarsall.bat file you should check if you have the key productdir in the registry: Return r"C:\Program Files (x86)\Common Files\Microsoft\Visual C++ for Python\9.0\vcvarsall.bat" For example: def find_vcvarsall(version): The easiest way to solve this problem is to remove the body (or just place in the first line) of the function find_vcvarsall(version) in the msvc9compiler.py file with the absolute path to vcvarsall.bat.

In case you do not have it, you can take a look at our previous article: Getting Started with MicroPython on ESP32 and ESP8266 to see how to install it easily. If you follow the function calls you will see is looking in the registry for the directory of the vcvarsall.bat file and it won't never find it because the function is looking in other directories different from where the above mentioned installation placed it, and in my case the registry didn't exits. Prerequisites Before installing Thonny IDE on your Windows, Linux and Mac based PCs make sure you have the latest version of Python3 downloaded and installed. The problem now is that a function find_vcvarsall(version) in the C:/Python27/Lib/distutils/msvc9compiler.py module is the one looking for vcvarsall.bat.
This will create the vcvarsall.bat in "C:\Program Files (x86)\Common Files\Microsoft\Visual C++ for Python\9.0" if you install it for all users. If it does not exits I recommend you to install Microsoft Visual C++ Compiler for Python 2.7. First you should look for the file vcvarsall.bat in your system.
