Hi there I have a weird problem with malwarebytes on my friends PC. It's running Windows XP SP3, and is up to date with MS updates. The symptoms are I can start mbam.exe, task manager shows it as running, but then it exits silently before any GUI appears, it works fine on my PC. I've completely removed it and reinstalled using a fresh download, the installer runs ok and even does an immediate update if I ask for it, but mbam again runs for a second or two then exits. I've worked through the FAQ and nothing there seems to solve the issue. I've even tried copying the contents of the malwarebytes folder from my PC to the other PC using a flash drive and running mbam.exe directly and I get the same result. I've got AVG free 2012 running quite happily, as well as Spybot 1.6.2 both up to date, running ok and not finding any infections on scans. I've downloaded and run the dds.scr program and they are in the attached zip file The PC seems to be working fine apart from this issue. Any suggestions gratefully received. attach & dds.zip
