Question

Recently I installed anaconda. Now, I uninstalled Anaconda and reinstalled python 3.6. I am not a able to install some packages because of the following error.

PermissionError: [WinError 5] Access is denied: 'C:\\Users\\DELL\\AppData\\Local

t\\run.exe'

This has been frustrating. I ran cmd with administrator too but other post aren't working for me. btw I have windows 7

Answer 1

The error message - "PermissionError: [WinError 5] Access is denied: '... Windows-32bit\run.exe'" suggests that a 32-bit version file is being run, and hence is being denied access.

The problem may get solved by removing the existing version of Python from Windows and then installing the 64-bit version afresh.

Tip for successful installation and hassle-free upgrade:

Manually create the installation directory with small path, without spaces and with 'write' permissions for installing python, instead of the default one offered by the installer.

The installer installs to C:\users\name\app data\...... This path usually causes problems while upgrading Python.

Tip:

Create a folder named C:\python3 (for installing python v3) and give 'write' permission to it to the user.

Select C:\python3 as the installation directory during the installation.

This will help install python and also upgrade it without hassles in the future.

Answer 2

When I faced the error, I closed cmd. I started cmd with administrator and fired the command nvm use 12.10.0 and it worked for me.
