I'm trying to install Silverstripe 3.1.3 on IIS 8.5, but I'm getting a bunch of failed file permissions requirements on the install page, such as "Does the webserver know where files are stored?" and other such requirements indicating that Silverstripe cannot see or write to it's own files and folders.
The site is running in it's own app pool, and I have given full file permissions on the website folder and subfolders to the application pool user, as well as IUSR for good measure.
I cannot think of what else I can do to fix this problem. Does anyone have any ideas? Thanks in advance.
