For some strange reasons, I'm unable to install procguard.sys during PG 3.405 installation so when I reboot I have the "Error in initialization" pop-up. I found on this forum a link to procguard driver for version 3.400 so I copied it to system32/drivers folder and after one reboot where the file was curiously deleted it now seems to work... But I'd like to know if there's a way to get the procguard.sys file for the proper 3.405 version, a web-link for example? thanks in advance... edit: problem solved by installing 3.410 version! *A mod can delete my post* Sorry for the inconvenience..
