Hello,
If you are getting this error while accessing your domain on the browser (after Node.js installation). Follow this step to fix this.
Error:
====================>>>
The iisnode module is unable to start the node.exe process. Make sure the node.exe executable is available at the location specified in the system.webServer/iisnode/@nodeProcessCommandLine element of web.config. By default node.exe is expected in one of the directories listed in the PATH environment variable.
====================>>>
Fixed:
====================>>>
Create a symbolic link from the 32-bit path to the 64-bit one.
At the cmd.exe prompt:
mklink /D "C:\Program Files (x86)\nodejs" "C:\Program Files\nodejs"
====================>>>
or try placing this at the bottom of web.config
<iisnode watchedFiles="*.js;node_modules\*;routes\*.js;views\*.jade"
nodeProcessCommandLine="\program files\nodejs\node.exe"/>
Thank you,
