Possible solution:

Inside TM1 Architect, ensure you use FQDN server names to connect to TM1 servers.

Select File and Options

At login parameters at admin host field ensure you have written servername.domain.com instead of only server name.

Change and try again.

Check that the IBM Cognos TM1 Server version of the file C8ITKShared.dll

is exactly the same as the one on the TM1 Architect client computer.

If they are not the same version, you can get this error.


On the client computer you have installed the TM1 client’s files, and the TM1 Architect files in different folders.

Add the path to the TM1 Bin folder for the client files to the PATH variable in Windows.

Right click on My Computer and select  Properties.

Click on Advance System settings

Click on Environments Variables

Mark PATH and click on EDIT.

Add  C:\Program Files (x86)\IBM\Cognos\tm1_api\bin to the Variable Value

Click OK

Click OK

Click OK

Logoff  the computer and login again.

The path to the bin folder can be different in your installation.
