    3050 couldn't lock file

    i went to run subjects on a questionnaire as usual. however, media lab would not open the questionnaire. instead i got a message "3050 couldn't lock file." what does this mean and how do i correct it?

    If you log on to Windows as an administrator and THEN try running
    it, does the problem go away? Are you running this off a network drive?

    I'm still have this problem. I was never logged on as an administrator and didn't previously have this problem...

    Another case:

    When I run the sample1 data file according to the online tutorial, I get this error message 3050 couldn't lock file.
    Did you confirm read/write access? An easy way to tell if that's it is to run it as an Admin--if it then works, the trouble is usually read/write permission. Can you try a second machine to see if the error replicates?

    Once the permissions were changed on the Media Lab folder, the application functioned as expected.
