I had to logon to a client’s computer today to have a look at an issue with some software I’d created. They have LogMeIn on all their computers and I got the error “LMIRfsClientNP.dll is not a valid windows image” when I logged on. I fairly quickly found that this is caused by LogMeIn itself. So I connected to their VPN, then RDP’d in to the problematic PC, uninstalled LogMeIn and reinstalled it and the problem went away.
