  • Option 1
  1. Remove the 32-bit version of Microsoft Office. 
  2. Install the 64-bit version of Microsoft Office
  • Option 2
  1. Uninstall any version of the Microsoft Access Database Engine earlier than 2016. 

 

  1. Download and install the following:
    • Microsoft Access Database Engine 2016 (64-bit)

https://www.microsoft.com/en-us/download/details.aspx?id=54920

    • Microsoft Visual C++ 2010 SP1 Redistributable (x64)

https://www.microsoft.com/en-us/download/details.aspx?id=13523

  • Option 3:

Check to ensure that antivirus definitions and rules allow the executable AceDriverTest.exe to run so that it can verify that the Access Database Engine is installed on the system.

  • Option 4:
  • The following registry key is related to AceDriverTest.exe failing to find Access Database Engine installed:

HKEY_LOCAL_MACHINE\Software\Classes\CLSID

{3BE786A0-0366-4F5C-9434-25CF162E475E}

\InprocServer32
{Default}

  • If issue started after recent Microsoft Office updates, the path is:

C:\Program Files\Microsoft Office\root\VFS\ProgramFilesCommonX64\Microsoft Shared\Office16\ACEOLEDB.DLL.

  • The version of ACEOLEDB.DLL is 16.0.15128.20112.
  • Changing the path to the following will fix the launch issue: C:\Program Files\Common Files\Microsoft Shared\OFFICE16\ACEOLEDB.DLL   (File version 16.0.5011.1000)
