404 not found error after the upgrade of the Windows infrastructure app

[corti77]

Running Splunk 8.1.4 and Splunk app for Windows Infrastructure 2.0.1. I tried to upgrade to 2.0.4 and after restart splunk service I get the error 404 when I try to access the App.

checking splunkd.log I see the following:

ERROR PropertiesMap - Cannot open: C:\Program Files\Splunk\etc\apps\splunk_app_windows_infrastructure\default\data\ui\html\customize_features.html: The system cannot find the path specified.

Checking the file system, the folder html is not present . could someone explain me what is happening?

I manually install the app and after restarting splunk, the folder finally appeared.

thanks a lot!

Your app upgrade failed, and did not install all the required files under default.
check your file system permissions, maybe a write permission is lacking,

If the UI upgrade failed,  an alternative solution is to do a manual upgrade 

1.  stop splunk
2.  get the windows app installer (.spl or .tar.gz)
3. and manually untar it in your SPLUNK_HOME/etc/app folder (it should overrite your windows app folder)
   
   
4. verify that the html files are now present
5. then restart splunk and retry.
