"Error connecting to Acctivate database: Provider cannot be found" during Mobile WMS installation

Learn how to resolve the “Provider cannot be found” error when installing Acctivate Mobile WMS web service without Acctivate installed.

This error occurs when running the Acctivate Mobile WMS Web Service installer on a system that does not have the Acctivate desktop client installed. The installer relies on the Microsoft OLE DB Driver for SQL Server, which is not present by default on all systems.

You may see the following error message during installation:

Error connecting to Acctivate database: Provider cannot be found. It may not be properly installed.

This indicates that the required database driver is missing. To resolve this issue, follow these steps:

  1. Download the Microsoft OLE DB Driver for SQL Server using the link below:
    Download msoledbsql.msi (version 18.6.5.0, x64)

  2. Run the downloaded .msi installer to install the OLE DB driver.

  3. Once installation is complete, restart the Acctivate Mobile WMS Web Service installer.

  4. The error should no longer appear, and installation should continue successfully.

Expected Result:
The installer connects to the Acctivate database and completes setup without error.

Actual Result:
The installer shows an error stating the database provider cannot be found due to the missing OLE DB driver.

If you continue to experience issues after installing the driver, verify that you're using the 64-bit version and that your system meets the driver's prerequisites.
