You do not need to remove the exe. If you are not using the service simply disable it. 

Edit the  "C:\Program Files\Qlik\Sense\ServiceDispatcher\services.conf" file

Set

[nl-parser]
Disabled=true
[nl-broker]
Disabled=true

This will improve performance

Hi

Are you using Natural Language in your environment?, if not, you can disable it, please refer to the following article: https://community.qlik.com/t5/Knowledge/nlparser-r-exe-error-in-Windows-Event-log-using-Qlik-Sense/t...

"On systems with a limited amount of RAM, the nl_parser may also consume too much memory for the system to manage and needs to be disabled."

Hope it helps!
