I get a message saying that I don't have appropriate permissions to install an extension
I get this message only on some extensions I try to install. Others install just fine. Other times I get a message saying that there was an internal error and that the extension won't be installed, even though the extension is for Dreamweaver CS4, which is what I'm using. These are for both extensions that are free and ones I have paid for. I am the admin on this workstation, so I can't understand why I get these messages, especially for the one about permissions. I am using a Dell PC with Vista Home Premium 32bit.
