Hi ​@TheExpert,

Can you check the system requirements (not only OS but also the additional software that is needed)?

System Requirements - Veeam ONE User Guide

When everything fits you can try to re-download the ISO, reboot the server and try again (simplest approach).

In case that doesn’t help I recommend opening a Veeam support case.

Additional I cannot recommend running Veeam services on Windows client OS since you will have issues when it comes to performance, stability and hardening (security in general) so you should consider moving to Windows server OS for these critical DR workloads.

Best regards

Lukas

​@lukas.k: Thank you. Because of using the FREE edition of Veeam ONE in a homelab, Windows 10 is enough and worked without issues in the past. I already tried the installattion after a reboot but that doesn’t help. The installation starts with the postgres database for the reporting services without issues. Then it comes to the installation of the monitor client which isn’t starting because of wrong the path.

And Windows 10 22H2 is still supported with Veeam ONE 13: “Microsoft Windows 10 version 1909 and LTS builds (Minimum supported version 21H2 for LTSC channel and 22H2 for GA)”

​@TheExpert - hmm...haven’t come across any issues with VONE v13 upgrade as of yet. Is this a physical device you’re attempting to install on? If you have the means of using a VM, can you attempt installing in same OS on VM & see if it’s successful. I assume you at least looked over the Upgrade part of the VONE Guide?
https://helpcenter.veeam.com/docs/one/userguide/upgrade.html?ver=13

If not...at least worth glancing at to see if something stands out. You could also try looking at some logs located at: %ProgramData%\Veeam\Veeam ONE\Logs\ or %ProgramData%\Veeam\Setup\

See: https://www.veeam.com/kb1862

Hope that helps.

Best.

​@coolsport00: This is already a VM. I tried the installation with the ISO file located on a local drive on the VM and also located on my NAS. It’s always the same behavior: The installation of the monitor client doesn’t work.

Regarding the logs I didn’t find a log that points to the failing installation of the monitor client. And this is plausible because the installation of the monitor client couldn’t start.

I’m out of ideas ​@TheExpert , aside from contacting Veeam Support.

​@coolsport00: But for the FREE edition there’s no support, right?

There is support for free ed, but it’s “best effort”; in other words, if they have the time to assist, they will.

I’m not able to open a support ticket because the system still has a mail address saved that isn’t available any more and do not find where this address is saved to change it.

In the past updating of Veeam ONE was no problem. I don’t understand why this isn’t working today.
