I've been having problems running MeV on my 64 bit windows 7 computer.
I have updated my Java and my Java runtime environment and if I choose run as administrator the viewer will come up if I click on MeV.exe but not if I click on TMEV.bat (even if I try going through the command prompt to run the program. I have currently placed the folder that it unzips in under C: so there shouldn't be issues with it being under a folder like Program Files. And yet when I try to open a data file all it does is lock me out of the program entirely (I need to start Task manager to actually close everything). I suspect this has to do with some update to windows 7 or Java, since MeV was working on this computer in December when I last used it.
