2026-10-30 13:55:46,551 INFO [6ae4a1e285174de67b1d0] error:331 - Masking the original 404 message: 'The path '/en-US/static/@b2ae2962645c/build/pages/enterprise/remoteApps/app_listing/4.latest/version.json' was not found.' with 'Page not found!' for security reasons
Windows:
Run a Powershell session as Administrator so the Splunk installation is accessible. Run this command. Adjust the drive letter and install location if required:
dir “c:\Program Files\Splunk\share\splunk\search_mrsparkle\exposed\build\pages\enterprise\remoteApps”
If the file is not found, the remoteApps folder is missing from the install despite file integrity checks marking everything OK.

MacOS:
Look for the remoteApps directory in $SPLUNK_HOME/share/splunk/search_mrsparkle/exposed/build/pages/enterprise/:
ls $SPLUNK_HOME/share/splunk/search_mrsparkle/exposed/build/pages/enterprise/
If remoteApps isn't returned in the results, the remoteApps folder is missing from the install despite file integrity checks marking everything OK.
Windows:
mkdir “c:\Program Files\Splunk\share\splunk\search_mrsparkle\exposed\build\pages\enterprise\remoteApps”
Create a symlink in that directory to the app_listing directory in Splunk. There are 2 drive letters in this command, so be sure to change both if Splunk is not installed in C:\Program Files:
New-Item -ItemType SymbolicLink -Path "C:\Program Files\Splunk\share\splunk\search_mrsparkle\exposed\build\pages\enterprise\remoteApps\app_listing" -Target "C:\Program Files\Splunk\lib\remoteApps\app_listing"
No restart is required. The manage apps page will load after making these changes.
Mac OS:
mkdir $SPLUNK_HOME/share/splunk/search_mrsparkle/exposed/build/pages/enterprise/remoteApps
ln -s $SPLUNK_HOME/lib/remoteApps/app_listing $SPLUNK_HOME/share/splunk/search_mrsparkle/exposed/build/pages/enterprise/remoteApps/app_listing
