Issue

I have recently installed Quicktime and since then I've got the "hello" folder containing "mdnsDSP.dll and mdnsresponder" files, settle in my Program Files.

When I try to delete this folder, it prompts me with the following error message:"Access Denied".

Solution

The problem may be due to some administrative rights.

Open Explorer.

Tools.

Folder Options ...

View Tab.

Down in the list uncheck "Use simple file sharing (recommended)".

Right click on the folder or file for which you do not have access, "Properties". Security tab. Advanced Settings. "Owner" tab.. Select User. Check the following option: "Replace owner on sub containers and objects". Click on "Apply".

Try to delete the file again!
