'microsoft.ace.oledb.12.0' Access Denied When Exporting Data To Excel 2007

I have a stored proc that runs and produces an Excel 2007 file. I can run it fine within SQL Server Management Studio.
Basically, this is a partial code in the stored proc:


-- export sql server table data to excel 2007

insert into OPENROWSET('microsoft.ace.oledb.12.0',

'Excel 12.0;Database=D: emp est2007.xlsx;',

'SELECT * FROM LicensesrRegion') select * from Licenses

BUT when I have an execute SQL task to run that stored proc in an SSIS package, I received the following error:
Ad hoc access to OLE DB provider 'microsoft.ace.oledb.12.0' has been denied. You must access this provider through a linked server.

Please advise.

PS: I have to run that stored proc in an SSIS package because the SSIS package does some prereq stuff ( create folder, copy template to new Excel output file) then finally calls the aforementioned stored proc.

Thank you in advance.

Thanks!
