If the account being used to run the installer does not have the 'Debug programs' security setting, it can cause the fresh install of Veeam ONE or Veeam Service Provider Console to fail during the 'Installing Microsoft SQL Server Express' stage. In this case, the installer may not display the error message mentioned above. Instead, it fails with the message 'Setup Failed'.
If you encounter this issue, running the SQL Express installer on its own may display the following prerequisite error:
Rule "Setup account privileges" failed.
The account that is running SQL Server Setup does not have
one or all of the following rights: the right to back up files
and directories, the right to manage auditing and the security
log and the right to debug programs. To continue, use an
account with both of these rights. For more information, see
