I have node installed in my machine with windows 10, however i found something weird with the node.

When doing node -v from the command line, i got the running version is v0.10.28, but i am sure i have upgrade the node by downloading the node from the node.js which is the version is V4.4.7. So i tried to uninstall the node from the apps and feature, the node was removed, but through command line, i still able to do node -v and return the same version, tried to restart the machine and still the same.

Anyone know how to solve this?

Try look for these folders and remove them (and their contents) if any still exist. Depending on the version you installed, UAC settings, and CPU architecture, these may or may not exist:

  • C:\Program Files (x86)\Nodejs
  • C:\Program Files\Nodejs
  • C:\Users\{User}\AppData\Roaming\npm (or %appdata%\npm)
  • C:\Users\{User}\AppData\Roaming\npm-cache (or %appdata%\npm-cache)

Check your %PATH% environment variable to ensure no references to Nodejs or npm exist.

  • there is one folder reside in `C:\Program Files\Nodejs`, thanks for your help – Joseph Goh Jul 27 '16 at 02:46
  • You're welcome, I got same problem on my Linux, so I understand your feeling about that. – mosesmeirelles Jul 27 '16 at 02:47
  • just wonder why the new downloaded node is installed in `C:\Program Files (x86)\Nodejs` instead in `C:\Program Files\Nodejs` while the installer is for `x64`? – Joseph Goh Jul 27 '16 at 02:48
  • According this [issue](https://github.com/nodejs/node/issues/2951) it's a conflict about the older version installation – mosesmeirelles Jul 27 '16 at 02:52
  • I also had to run MicrosoftProgram_Install_and_Uninstall to fix the nodejs installation - https://support.microsoft.com/en-us/help/17588/fix-problems-that-block-programs-from-being-installed-or-removed – tkit Jul 22 '17 at 16:27

I guess you have multiple nodejs installations on your system. You should run echo %PATH% to see, which is the first nodejs path.

To prove my guess, you can just goto the 4.4.7 installation folder and then run node -v to see the version number. I'm positive you will get 4.4.7.

  • there is one folder reside in `C:\Program Files\Nodejs`, just wonder how can i end up with 2 installation, and why did the new version of node that i downloaded from nodejs installed in `C:\Program Files (x86)\Nodejs` instead in `C:\Program Files\Nodejs` ? – Joseph Goh Jul 27 '16 at 02:47
  • Hum... You have both 32bit and 64bit installations. No matter how they came, you can first uninstall nodejs from control panel and then remove both directories, if any of them exists. And then run a clean install. – stanleyxu2005 Jul 27 '16 at 03:01
