I watched your video and you never checked or killed Continuum processes that are still running. Make sure that no Continuum processes are active in memory (use the task manager) before trying out things like disabling software. If there is already a Continuum process active, Continuum won't start up for the second time since it has protection not to allow multiple Continuum clients run at the same time. Have you tryed running an older Continuum client, like Continuum 0.38 and Continuum 0.39pr1? If both of these work then something new added to Continuum 0.40 is causing your problem. Since we "know" what has changed per version, you can narrow down your search for the problem. Yes before this topic was made I downloaded continuum039pre1.msi and same problem. Also I didn't show the processes in the video becasue of my username yah.. personal. Nut there is no instance of continuum It shows up for a little less then a microsecond you can barely see it if u dont press and hold enter key on the continuum shortcut which runs it 1000 times then you will be lucky enough to see it in task manager but yah.. it kills it self before it even initializates which tells me it isn't a file dependency problem aka.. no file missing etc.. just means something is preventing it like ollydebugger but I haven't installed any debuggers programming langauge compilers nothing like that its a fresh pc. Honestly this is something really stange if only I could unpack continuum I could probbly fix it my self by patching the checks but haha well dunno what works out I really don't care but I do miss continuum
