When opening an analysis file in the TIBCO Spotfire installed client that is access a flat file, the opening of the file may fail with the following error:

Error message: Could not open data source.

When the TIBCO Spotfire installed client is accessing an external data source like a file (.csv, .xlsx, etc), a temporary sub-process will be spawned so that the data access is not handled my the main application process (this has a few benefits including increased stability). If that spawned process is blocked when Spotfire is trying to access it, the above error will be seen.

The sub-processes launched by Spotfire for data access are named like "Spotfire.XXXX.exe" and are created in the temp folder (%LOCALAPPDATA%\Temp\TIBCO\Spotfire\) on the Spotfire installed client machine. To resolve this issue, those processes must be allowed to execute from that location by the group policy. To view the sub-processes and their paths, open Task Manager to see the Spotfire related processes that are triggered when you open the analysis for the first time. 

When the TIBCO Spotfire sub-process that is spawned when trying to access a file is blocked, opening the file in Spotfire fails with error. The sub-processes are launched from local machine temp folder (%LOCALAPPDATA%\Temp\TIBCO\Spotfire\)
