Just bought a Quad core Acer computer with pre-installed Vista Home Premium 64 bit OS. I wanted to modify a folder of a program that my friend created and I installed it in Program Files folder to test. Now when I try to modify a file, I get the message "Permission Denied" message even though I have admin previllege. I unchecked the "Read Only" box in the Folder properties box but it keeps on reseting to Read Only again. I checked with other folders and they are the same. How can I get rid of this Vista annoyance? Please advize!
