The error message "The 'Microsoft.ACE.OLEDB.15.0' provider is not registered on the local machine" suggests that the required OLE DB provider for Excel is not properly installed or registered on your system. Here are the steps you can follow to resolve this issue:
Install the Microsoft Access Database Engine:
- Download and install the Microsoft Access Database Engine 2016 Redistributable. This will include the necessary OLE DB providers.
- You can find the download link here.
- Make sure to download the version (32-bit or 64-bit) that matches your SQL Server Management Studio (SSMS) installation.
Check SSMS Version and Architecture:
- Ensure that the version of SSMS you are using matches the architecture of the Microsoft Access Database Engine you installed. If you installed the 64-bit version of the Access Database Engine, ensure SSMS is also 64-bit.
Re-register the OLE DB Provider:
- After installing the Access Database Engine, you may need to re-register the OLE DB provider. Open a command prompt as an administrator and run the following commands:
```powershell
shCopy code
regsvr32.exe
```
- Adjust the path to the `ACEOLEDB.DLL` file based on your Office installation directory and version.
**Verify Installation**:
- After installation, verify that the OLE DB provider appears in the list of providers in SSMS. You should see entries for `Microsoft.ACE.OLEDB.12.0` or `Microsoft.ACE.OLEDB.16.0`.
**Configure Data Source in SSMS**:
- When using the Import and Export Wizard in SSMS, ensure that you select the correct OLE DB provider (e.g., `Microsoft.ACE.OLEDB.16.0`) for the data source.
**Check for SSIS Installation**:
- While SSIS (SQL Server Integration Services) is not directly related to the OLE DB provider registration, ensure that you have the necessary components installed. You can try reinstalling SSIS if you suspect that its absence might be affecting your setup.
**Run SSMS as Administrator**:
- Sometimes, running SSMS with elevated privileges can resolve issues related to provider registration and access.
**Check Office Installation**:
- Since you mentioned you reinstalled Office apps as 64-bit, ensure that there are no remnants of the 32-bit installation that might be causing conflicts.
By following these steps, you should be able to resolve the issue with the Microsoft.ACE.OLEDB.15.0
provider not being registered on your machine. If the problem persists, ensure that there are no additional configuration issues or system restrictions that might be affecting the registration of the OLE DB provider.
