Splunk remote upgrader Windows update issue

Solitus31 — Wed, 15 Apr 2026 11:33:24 GMT

Hello,

we are trying to use splunk_app_uf_remote_upgrade_windows to upgrade our UF using Deployment server.
I have installed version 1.0.2 and trying to update application to last packages 1.0.3

Actual state information (same for all servers):

All servers installed with same powershell script
Package installation directory is "C:\Program Files\splunkupgrader"
Service is correctly executed by "Local Admin"

Update process used:

Add on DS packages 1.0.3 on local folder application
Reload class to deploy it.

For unknown reason, some UF failed to update remote upgrade application and i found the following error log message on splunk_upgrader_upgrade.log :
"ERROR Cannot find path 'C:\Windows\system32\2025-10-16-11-25-25' because it does not exist."

It's seems that where script "history.ps1" is executed, the $PSScriptRoot (defined on constants.ps1) is "C:\Windows\system32" instead of script directory ("C:\Program Files\splunkupgrader\bin").

Do you have some idea to solve this issue ?

I've tried to modify constants.ps1 on package 1.0.3 but (as expected) i have a signature check issue.

Hi @Solitus31

I have seen this issue with another customer and I think they had it confirmed via support that this was a bug but I cannot find the reference at the moment.

Are you able to try this with 10.0.5 and see if this resolve your issue? If not, I would recommend reaching out to Splunk Support at https://splunk.com/support with details of the issue and see if they can provide a workaround to bring you up to date.

Thanks for your reply.
I will investigate with Splunk support to understand why their is no issue when installation is done manually and why for unknown reason some server upgrade failed.
If something is found and issue solved, i will put information here too.
