Hello,
There could be a SQL Server security roles (permissions) issue for the related Windows account. Could you try to manually run the same SQL script content you try to run within the setup package when logged in SQL Server under the related standard user account? For instance you could try this operation by using the SQL Management Studio.
If this is still of no help, then to further investigate this, can you please send us the .AIP (project file) and a
verbose log of the installation to
support at advancedinstaller dot com so we can investigate them?
All the best,
Daniel
