Problem:

The following message, “‘OraOLEDB’ Oracle provider is not registered on the local machine,” appears when the Barcode Label Software encounters an Oracle Database Link Error.

Solution:

This is an authentication problem that can be resolved as follows:

1. Open Explorer and select the ORACLE_HOME directory, e.g. c:OracleOra92
2. Right-click on the directory and look at its properties.
3. Go to the Security tab and select Authenticated Users.
4. Unclick and then re-click the Read & Execute permission under the Allow column.
5. Click the Advanced button and ensure that the Authenticated Users entry allows Read & Execute on Folder, Subfolders, and Files.
6. Click OK and then Apply.
7. Reboot the machine, and the error should no longer appear.
8. More information about this error is provided on the OraFAQ Site.
