Hi @Arun Das 

Is there anything in the Windows Application Event Logs?

Hi,

No, I do not see anything in the application logs.

There are a lot of “Windows Error Reporting” events with ID 1001, this indicates a possible issue with your antivirus software.

Please have a look at this KB article and see if it helps.

Hi MattM,

Thank you for the update, I will look at the article, would also check if antivirus software is blocking Veeam.

@Arun Das - is this an initial install on a new server or reinstall? You're not using SCCM to do the install are you? I noticed you're using the Trace Tool is why I ask. 

Also, what server OS are you attempting install? 

Hi coolsport00,

This is a Reinstall from version 9.5 to 11a and not using SCCM for install.

OS version is windows 19.

Before you can upgrade, you must be on the correct patch for 9.5. See the Veeam KB on upgrade paths for more info. 

Hi coolsport00,

I have uninstalled Veeam 9.5 U4 completely and installed Veeam 11.0.1.1261_20220302. Upgrade was not an option as I did not had an active license.

Ok, I see. There is another who posted a couple days ago attempting to do the same thing....uninstall Veeam then install a newer version & getting errors. As I'm checking that post... I notice it was you. Did you contact support for assistance? Can you just reformat your server & reinstall the OS & attempt a fresh Veeam install? 

Hi coolsport00,

Yes, that was a similar case but different issue and error. I did open a case with Veeam awaiting update for this, so thought would also check on the Community if someone else faced the same issue.

Ok. Also, is there a reason why you’re not installing v12? Since you’ve uninstalled the previous version, upgrade paths don’t matter. You can just install the latest Veeam version.

Also, is there a reason why rebuilding your server isn’t an option? If you’re like me, I understand wanting to get a resolution for the error...I’m that way...but after so much troubleshooting without resolution, there comes a time to just bite the bullet, let go of troubleshooting efforts, and start from scratch.

I presume that something of the old installation are causing this. Why don’t you install Veeam on a new server with a new installation of Windows? How @coolsport00 sayed maybe v12 is a better option.

You may also need to uninstall Microsoft Visual C++ Redistributable and / or upgrade to newer versions, together with .NET Framework.

I’d start with building a new server if the one you are installing on is no longer needed

Hi dips,

Thank you will try this.

Despite created for analysing SCCM logs, you can actually use it in viewing logs from other sources. I use it in viewing MDT logs as well.
