Upgrading apps to WAB 2.7 ?

[chintakandel]

In Command Prompt window, I navigate to WAB 2.7 \server directory and type this command:

node_x86 upgrade D:\arcgis_web_appbuilder_2.6\WebAppBuilderForArcGIS

Error: ‘node_x86’ is not recognized as an internal or external command.

Again tried, 

node_x64 upgrade D:\arcgis_web_appbuilder_2.6\WebAppBuilderForArcGIS

Both command throws same error.

Command works until WAB 2.6. I wonder whether it is due to Node version or something different in WAB 2.7?

I checked Node version in my computer: V 5.7.1

Any thoughts?

Thanks in advance!

Chintamani,

  Did you open the cmd.exe using elevated privileges (i.e. right click and choose run as administrator)?

Hi Robert,

Thank you for your suggestion. I installed WAB in D drive. It was working without elevated privileges for WAB 2.5 and 2.6.

I always use elevated privileges and I just tested upgrading 2.6 to 2.7 and it worked fine for me.

Thank you Robert. I will use elevated privileges to upgrade apps.
