Hello @Anderson Wavrik ,
Thank you for reaching out with your queries.
"For the first issue, I need more, details on this application and its usage.
Q: I have a application that need some permission to access some files. But i can't access it."
For the second issue, can you please give full control to the user account you have used to log in to the server while installing this IIS set up and also ensure the system account/user account used has full access under C:\Program Files\llS\IIS Administration\"
The set up is trying to access the contents from this path and currently accessing this dll "Microsoft.AspNetCore.Antiforgery. dll"
