To disable subprocesses in a Spotfire client, open the following file:
C:\Program Files (x86)\TIBCO\Spotfire\X.X.X\Modules\Spotfire DXP Forms_XX.XX.XXXX.XXXX\Spotfire.Dxp.Main.dll.config
where the Xs represent the version of Spotfire being accessed. In the <applicationSettings> section, add the following code block:
<applicationSettings>
...
<Spotfire.Dxp.Data.Properties.Settings>
<setting name="DataImport_LoadOutOfProcess" serializeAs="String">
<value>False</value>
</setting>
</Spotfire.Dxp.Data.Properties.Settings>
...
</applicationSettings>
This may affect the stability of the client as crashes that would only bring down a sub-process will likely crash the whole client after this change. The same tag can be added to web.config to disable the same setting in the Web Player.
