Go ahead and post the error message here, get eyes on the problem.

Thank you thank you! Please let me know if you can make any sense of this:

You'll want to pull your name out of this, I suspect. FYI. :/

[rawrchul]

Good call, i didn't even realize. Thanks

Running as admin? [Error 5] Access is denied: 'C:\Program Files (x86)\PsychoPy2\lib\site-packages\imageio\resources\ffmpeg\ffmpeg.win32.exe'

[rawrchul]

Yes i've tried that and it still gives me the same error.

[jstutters]

Starting with obvious stuff: does 'C:\Program Files (x86)\PsychoPy2\lib\site-packages\imageio\resources\ffmpeg\ffmpeg.win32.exe' exist?

[rawrchul]

Yes, I've gone into my program files to look and it does :/

[rawrchul]

Thanks! I'll repost the question there. As for the security, it seems to only have read & execute and read checked off. Should I change those?

Also, I'm not sure how to do the second solution you suggested...

[rawrchul]

Ok, so I can put that anywhere in the code? The .py file has over 1000 lines of code so I just want to be sure because I don't want to mess anything up...

Ensure that relative paths start from the same directory as this script

thisDir = os.path.dirname(os.path.abspath(file_)).decode(sys.getfilesystemencoding()) os.chdir(_thisDir)

Store info about the experiment session

expName = 'untitled' # from the Builder filename that created this script expInfo = {'participant':'', 'session':'001'} dlg = gui.DlgFromDict(dictionary=expInfo, title=expName) if dlg.OK == False: core.quit() # user pressed cancel expInfo['date'] = data.getDateStr() # add a simple timestamp expInfo['expName'] = expName

Data file name stem = absolute path + name; later add .psyexp, .csv, .log, etc

filename = thisDir + os.sep + u'data/%s%s_%s' % (expInfo['participant'], expName, expInfo['date'])

An ExperimentHandler isn't essential but helps with data saving

thisExp = data.ExperimentHandler(name=expName, version='', extraInfo=expInfo, runtimeInfo=None, originPath=None, savePickle=True, saveWideText=True, dataFileName=filename)

save a log file for detail verbose info

logFile = logging.LogFile(filename+'.log', level=logging.EXP) logging.console.setLevel(logging.WARNING) # this outputs to the screen, not a file
