Hi
I'm using ruby 2.2.4-p230 and Watir WebDriver on Windows 7

I got noticed that when execute my Ruby script in a Chrome WebSite always the "Remember logins for sites" is disabled even when the default profile is not.
All this do not allow me to complete my script because my script must download and execute a .exe automatically.

I´m suspecting that the ruby interpreter or the ChromeDriver, is executed with a user with less security privileges.

Can someone know something about it, to solve this issue?

What I have tried:

After some hours, surfing on the web

I did with 2 option:
*** ON FIREFOX ***
Option 1
myprofile = Selenium::WebDriver::Firefox::Profile.new
myprofile['dom.disable_open_during_load'] = false
myprofile['browser.download.downloadDir'] = 'C:\\Any_path_differente_download'
myprofile['signon.rememberSignons'] = true

$b = Watir::Browser.new(:firefox, :profile => myprofile)

Option 2
$b = Watir::Browser.new :firefox, :profile => 'mycustomProfile'

**** ON CHROME ****
Option 1
prefs = {
:download => {
:prompt_for_download => false,
:default_directory =>"c:/Any_path_differente_download/"
}
}
switches = %w(--ignore-certificate-errors --disable-popup-blocking --disable-translate --disable-internal-flash)
$b = Watir::Browser.new :chrome, :prefs => prefs, :switches => switches

Option 2
$b = Watir::Browser.new :chrome, :profile => 'default'
