Why Can't My SQL Server Instantiate the OLE DB Provider for Linked Server Exports to Excel?

Unable to Instantiate OLE DB Provider for Linked Server

Problem:

When attempting to export data from a table to Excel using a T-SQL query, the error "Cannot create an instance of OLE DB provider Microsoft.Jet.OLEDB.4.0 for linked server null" occurs.

Cause:

This error typically arises when:

• The user lacks sufficient permissions to access the temporary folder used by OPENROWSET.
• The 32-bit OLE DB provider (Microsoft.Jet.OLEDB.4.0) cannot be loaded in-process on a 64-bit SQL Server.

Solution for 64-bit SQL Server:

1. Download and install Microsoft.ACE.OLEDB.12.0 for Windows 64-bit.
2. Grant access to the temporary directory (C:WindowsServiceProfilesNetworkServiceAppDataLocalTemp for a network service account) to the account running SQL Server.

3. Enable Ad Hoc Distributed Queries and configure Microsoft.ACE.OLEDB properties:

   SP_CONFIGURE 'show advanced options', 1;
   GO
   RECONFIGURE;
   SP_CONFIGURE 'Ad Hoc Distributed Queries', 1;
   GO
   RECONFIGURE;
   EXEC sp_MSset_oledb_prop N'Microsoft.ACE.OLEDB.12.0', N'AllowInProcess', 1
   EXEC sp_MSset_oledb_prop N'Microsoft.ACE.OLEDB.12.0', N'DynamicParameters', 1

4. Register msexcl40.dll:

   regsvr32 C:\Windows\SysWOW64\msexcl40.dll

Additional Notes:

• For SQL Server 2014 and later, use "DynamicParameters" instead of "DynamicParam" in the EXEC sp_MSset_oledb_prop command.
• Ensure that the user running the query has the necessary privileges, such as "IMPERSONATE" and "ALTER ANY LINKED SERVER."
• If still encountering issues, check if "MessageBoxText" is set to "3" in the SQL Server Configuration Manager under "OLE DB Provider Settings."
