1. Open the Spotfire.Dxp.exe.config file which can be found in either of the following location,
a. C:\Program Files (x86)\TIBCO\Spotfire\10.10.3\
b. C:\Users\<uname>\AppData\Local\TIBCO\Spotfire\10.10.3\
2. Check the arguments section in the config file. It would be as below
<arguments>
<argument name="loadAllModules" />
</arguments>If this argument is present in the configuration file then the client will load all the modules available in the Modules folder defined the config file. If the unwanted module/custom extension has been previously deployed and downloaded then the client will load these module(s) though they are not part of the deployment area.
