No matter what i do i can not install any program that is in a zip file that ive downloaded from limewire. I have both Winzip and WinRAR and they both work perfectly. I can extract the program but whenever i try to install it it displays an error message saying "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item." I click OK and then a message from winzip says "File C:\Windows\Temp\install1\setup.exe is in use by another process. Cannot delete folder C:\Windows\Temp\install1\."
Any help would be much appreciated
