This might sound very silly, but I had taken a good amount of time to solve with this issue. While running the installer you might hit an error:
"TF220065: An error occurred while the Setup program was querying the settings from the server that is running SQL Server Reporting Services. This error is most likely caused by either a firewall or a network problem preventing a connection to the server that is running Reporting Services."
The "VSTF_RS_Server" value in the MSIProperty.ini file might have an incorrect value. This might happen if you were trying to originally set up a multi-tier Team Foundation server with a remote Reporting services instance and later settled down to go with a Reporting services instance on the application tier itself. If you wish to point the installer to use a remote reporting services instance, the pre-installation steps requires you to specify the remote server name as the value as the parameter for “VSTF_RS_Server” in the MSIProperty.ini file.
Open the MSIProperty.ini file in a editor (like notepad) and modify the value for VSTF_RS_Server with the name of the computer that runs the Reporting services component. If the reporting services component is running on the applicaiton tier, the value should ideally be [ComputerName]
Note: The value cannot be blank inside the square brackets.
1) Navigate to <Drive>:\AT\msiproperty.ini file
2) Open the msiproperty.ini file on a Note pad
3) Modify the value for VSTF_RS_Server as VSTF_RS_Server = [ComputerName]
4) Save and close the file and start the installation.
