Let me shortly describe the situation:
We have TM1 running on two servers. One with 9.4.1 and another one with 9.5.2. I am on a Client-Computer with no direct access to the server. Still, I would need to access both servers. To ensure this I have copied all the files from [Program Files]\Cognos\TM1 into a "back-up"-folder on my local hard disk. Then I was updating the Client-Software to 9.5.2.
Now I have two TM1-Folders (one in the Program Files path and one at a back-up folder on the hard disk). In each folders there's a bin folder containing the "tm1p.xla"-file. When clicking this either in the 9.4.1 or 9.5.2 file Excel opens with the according TM1 Client Version (Excel Perspectives).
Now the problem:
The 9.5.2. Version runs without additional problems (just the ones that everyone encounters

The question:
Does anyone else has a better idea on how to run two Perspectives versions on a client computer? Or maybe also an idea on how to fix this?
Any help or comments are very much appreciated. Thank you very much in advance. With best regards,
Konstantin
