• 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. 

2. 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)
