Can't install a OLE DB Provider for IBM DB2 ISeries on SQL Servers higher than 2008 version
If you want to use the Microsoft provider, you'd need to use the Microsoft provider's name and not IBM's provider name.

The IBM provider is/was part of Client Access for Windows.  You don't mention what version you are trying to install, but the latest is v7r1 and it supports up to Windows 8.1.

IBM has replaced client Access for Windows with the new Access Client Solution (ACS).  ACS is split into two packages, an OS independent package and a OS dependent one.

The OLEDB driver is part of the ACS Windows Application Package.

Both the Client Access for Windows and the ACS Windows application package are licensed software and available only through IBM's Entitled Software Support website (ESS).  You'll need your IBM i folks to download it for you, or help you get access.
