Upgrade 7.11.13 to 7.11.15 fails at systemcheck on windows

Note that it is also failing for files under SuiteCRM:

D:/CRM/SugarCRM/apps/SuiteCRM/htdocs.gitignore 0666 0 0
D:/CRM/SugarCRM/apps/SuiteCRM/htdocs.htaccess 0666 0 0
D:/CRM/SugarCRM/apps/SuiteCRM/htdocs.travis.yml 0666 0 0

As pointed out in:

this is a permissions error. For the webserver to view these files, it must have the appropriate permissions. As this is a windows system, the 0666 is a fake *nix translation for the users benefit.

You will need to identify the identity that the webserver runs at…I suspect that it will be apache or httpd, and ensure that the files concerned have security permissions to be read by that user.
