Downloaded Diablo 2 Installer Client, gets “Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item.” I have tried launching it with “Administrator,” and have tried Windows XP. I am running it on Windows 7, previously I was able to install it, now it does not even let me. I have also deleted the registry for Diablo 2, as well as removing the Folder under Program Files.
this seems like a Windows issue. are you trying to run an installer that is located in another person’s user folder? or from a network location (like a NAS or another computer connected to your home network)? i’d try re-downloading the downloaders/installers and trying again, or moving the installers to your desktop then running them.
Just wanted to chime in. I had this problem and moving the files to my Desktop resolved the problem.
