I tried all of these, and it finally worked! Sometimes, it can run very slowly at first, but you need to be patient. I think you need to free up space on the C: drive, which will not only improve its performance but also benefit your overall system performance. I also changed the version of Android while creating a new device. The one I had chosen earlier had 'not supported' next to it. I don't really know if it influenced anything, but in my case, it worked :)
