Installation problems Network Topology Mapper

Sounds about right to me, try installing NTM on a different windows box.

I have this same issue, I am not installing on the Orion server though.  Where can I see the error message it mentions?

Hello,

this workaround worked, while I am administrator :

in the NTM 2.3 Release Notes :
Non-administrator users cannot install NTM 2.3

Run PowerShell as administrator: Search for PowerShell in the taskbar, right-click Windows PowerShell in the search results, and click Run as administrator.

In PowerShell, go to the System32 folder.

cd C:\Windows\System32

Review the following command, replace with your location. If necessary, adjust the path to logs.

.\msiexec.exe /i "<installation file location, such as C:\Users\nonadmin\Downloads\NTM-2.3.0.50133\SolarWinds Network Topology Mapper.msi>" /L*V "C:\Users\nonadmin\Downloads\NTM-2.3.0.50133\SolarWinds Network Topology Mapper-msi.log"

Since I am already an administrator install shouln't fail, but with Solarwinds it's often special

regards

Hello fabrice.da 
Did this solution allow you to install and license NTM on the same server as your NPM main server?
I am prepping for a new NTM 2.4 installation to coexist on an NPM 2024.4 server. 

The last thing I want to do is break my current platform.

Thanks for any guidance.
