it didn't work while i replace $cdc_lasutopfhvcZLmcfl to anything try to avoid detected by some site via chromedriver.exe

Question

i had read this page Can a website detect when you are using selenium with chromedriver? and i follow the steps in that, but when i finish replace $cdc_lasutopfhvcZLmcfl to whatever_var , i can't lunch chrome by the driver edited, when i try to lunch it i got an error like this The application was unable to start correctly (0xc000007b)

it's that because the driver version i used with ChromeDriver 2.36.540470 ?

when i edit driver in vim after searching the var $cdc_lasutopfhvcZLmcfl, i find the source code was different with the page i mentioned before, it look like this:

function getPageCache(opt_doc, opt_w3c) {
  var doc = opt_doc || document;
  var w3c = opt_w3c || false;
  var key = '$cdc_asdjflasutopfhvcZLmcfl_';
  if (w3c) {
    if (!(key in doc))
      doc[key] = new CacheWithUUID();
    return doc[key];
  } else {
    if (!(key in doc))
      doc[key] = new Cache();
    return doc[key];
  }
}

any suggestion please ?

When replacing '$cdc_lasutopfhvcZLmcfl', you must make sure to replace it with a string of the same length (and probably the same structure too). So, you would want to use a replacement that would look like this: '$sws_01234567890123456'. All together, 17 chars after the underscore.
