After installation of veeam, you may encounter that services were not able to start.
The reason is probably in conflict with an existing application.
Example: 6161 is conflicting with other port
[To verify]
Open PowerShell and execute the command
Get-Process -Id (Get-NetTCPConnection -LocalPort 6161).OwningProcess
[Solution]
Open regedit, find the service port, and change it
