ssas – What version of MSOLAP provider am i using?

We’ve just upgraded a Server from SQL Server 2016 to 2019.

We have linked servers connecting to an OLAP cube.

When I look under providers for MSOLAP the label of the dialog box shows:

Microsoft OLE DB Provider for Analysis Services 14.0

If I look at a linked server The drop down for provider also says:

Microsoft OLE DB Provider for Analysis Services 14.0

When I look in: C:Program FilesMicrosoft Analysis ServicesAS OLEDB I have 2 folders:

If I look under 130 at the properties for MSOLAP130.dll it says it is version 13.0.5622.0

If I look under 140 at the properties for MSOLAP.dll it says it is version 15.1.65.24

Which DLL Is my linked server using? 13.xx or 15.xx?
