In our product we can interact with different datasource and one of these datasources was a Microsoft Access DB connected via OLEDB. This is really, really old, but still works, but on one customer machine we had this issue:
'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine
Solution
If you face this issue, you need to install the provider from here.
Be aware: If you have a different error, you might need to install the newer provider - this is labled as “2010 Redistributable”, but still works with all those fancy Office 365 apps out there.
Important: You need to install the provider in the correct bit version, e.g. if you run under x64, install the x64.msi.
The solution comes from this Stackoverflow question.
Helper
The best tip from Stackoverflow was these powershell commands to check, if the provider is there or not:
(New-Object system.data.oledb.oledbenumerator).GetElements() | select SOURCES_NAME, SOURCES_DESCRIPTION
Get-OdbcDriver | select Name,Platform
This will return something like this:
PS C:\Users\muehsig> (New-Object system.data.oledb.oledbenumerator).GetElements() | select SOURCES_NAME, SOURCES_DESCRIPTION
SOURCES_NAME SOURCES_DESCRIPTION
