Cognos TM1 does not support to be installed on Microsoft Windows Server 2008 standard. You must use Microsoft Windows 2008 R2.

Cognos TM1 version 9.5.1 support this

Cognos BI 8.4.1 support this

When you are going to integrate TM1 and Cognos BI you must install parts of TM1 on the BI server – therefore the Microsoft Windows OS must be supported by TM1 also.

Install a new server with Microsoft Windows 2008 R2.
