Why Can't I Create an OLE DB Provider Instance When Exporting Data to Excel?

Cannot Create OLE DB Provider Instance: Troubleshooting and Solutions

When attempting to export data to Excel through a T-SQL query, users may encounter the error "Cannot create an instance of OLE DB provider Microsoft.Jet.OLEDB.4.0 for linked server null." This error indicates an issue with creating an instance of the OLE DB provider required for the export operation.

Potential Causes:

• Insufficient user privileges to access the TEMP folder
• Incompatibility between the OLE DB provider and SQL Server architecture (e.g., 32-bit provider on 64-bit SQL Server)

Resolution:

1. Ensure User Permissions: Grant administrator privileges to the user running the query to enable folder creation in the C drive's TEMP folder, where OPENROWSET creates temporary files.
2. Configure Distributed Queries: Enable Ad Hoc Distributed Queries and configure the Microsoft.Jet.OLEDB.4.0 properties as follows:

EXEC master.dbo.sp_MSset_oledb_prop N'Microsoft.Jet.OLEDB.4.0', N'AllowInProcess', 1
GO 
EXEC master.dbo.sp_MSset_oledb_prop N'Microsoft.Jet.OLEDB.4.0', N'DynamicParameters', 1
GO 

3. Update OLE DB Provider: If accessing a 64-bit SQL Server, install Microsoft.ACE.OLEDB.12.0 for Windows (64-bit) and configure its properties using the following commands:

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'DynamicParam', 1

4. Register msexcl40.dll: For SQL Server 2014 and later, register the msexcl40.dll file:

regsvr32 C:\Windows\SysWOW64\msexcl40.dll

Once these steps have been followed, users should be able to successfully export data to Excel without the OLE DB provider instance creation error.
