I while ago my computer crashed and a file in my virus protector got lost in the recovery process. Because of this, I cannot uninstall, reinstall, or install a newer version of the virus protector. I've figured out what file went missing, and have downloaded the file. But when I try to move the file into the virus protectors folder, it says I need administrator permission it do it. I've seen things about changing permissions by going to properties-security-advanced, but even when I do that it just says access denied when it gets to the program files.
Any ideas on how to get into this folder so I can replace the lost file, uninstall the current virus protector, and install the new virus protector?
The file that is missing is rtl120.bpl
