Yes, I completely uninstalled Solus, I actually fully removed the SIMS folder to install and rebuild. I can see from the logs that pulsar.exe did infact stop:
The program Pulsar.exe version 7.224.27.0 stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Security and Maintenance control panel.
I'm fairly new to this (First year in IT) but this is the first time the issue has arisen.
