During the installation of the MIBs database update, you might encounter the following error message:

SolarWinds MIBs vx.x.x.xxxxx Setup Wizard ended prematurely because of an error. Your system has not been modified. To install this program at a later time, run Setup Wizard again. Click the Finish button to exit the Setup Wizard.

Under MIB Management, the following message appears:

Failed to determine MIBs database status when trying to update the MIBs database

 

Orion Platform

This issue occurs when one of the following conditions is true:

• The file “C:\ProgramData\SolarWinds\MIBs.cfg“ or “C:\ProgramData\SolarWinds\MIBs.db“ is being held by a running process.
• The file “C:\ProgramData\SolarWinds\MIBs.db“ was accessed during the MIBs database upgrade process.
• All SolarWinds Services are not shutdown properly

To resolve this issue, please upgrade to SolarWinds Platform 2026.1.1 or later.  If an upgrade is not possible, please perform the following steps:

1. Stop any service that is blocking access to MIBs.cfg or MIBs.db file.  This is typically the SolarWinds Orion Module Engine.
   • If the problem persists, it is recommended to stop all SolarWinds services
2. If file “C:\ProgramData\SolarWinds\MIBs.db“ exists but has a size of 0 bytes, delete it.
3. Run the MIBs installer again as administrator
   

Alternatively, please try the following steps:

1. Open up an Administrative Command prompt and run this command, replacing the path to where your *MIBsv2.msi is. It is located in C:\ProgramData\Solarwinds\Installers\ by default.

msiexec /i "C:\programdata\Solarwinds\Installers\MIBSv2.msi"

OR
msiexec /i "C:\programdata\Solarwinds\Installers\Observability-<SolarWinds Ver You are installing>-MIBsv2.msi
