That's not a good idea, doing so would most likely cause modules not to load.
Do you get the error if you attempt to open ESET's gui after installation or only after a restart? What operating system do you use?
I'm using Windows 7 64bit. If I try to open the ESET GUI whilst the Eset Service module is not started, I get the Kernel Error. However once I manually start the Eset Service module, I can then open the ESET GUI. ESET will then continue to run normally until my next reboot.
