I have downloaded and isntalled a few sidebar gadgets in the past, but now, it will not let me install any new ones. The problem started out when vista didn't recognise the .gadget file. So I serached around a bit to try and find a solution. There was another thread I found (not on here) where someone was having the same problem but never found a solution. I've assosciated the .gadget files to the windows sidebar application but still nothing. I tried make the file a .zip file and unpacking the files manually but that didn't work either. I've tried a few other things as well but I can't remember what they were. The strange thing is, is that I was able to install gadgets a while ago and had no problem with them, but now it refuses to install them. I've tried gadgets both from this sight and the official microsoft gadget site. Can someone please shed some light as to what's happening here. Thanks in advance for any help.
