My company needs to purchase Visual Studio. We have a previous version that is licensed but anyone that would know who it's registered too is long gone. We are also unable to confirm purchase, we believe a outside company installed it. We are still trying to verify purchase, it is a older version.
We need the key to get upgrade pricing. I am able to retrieve all keys but is there a way to confirm that we own it or who the owner is without contacting Microsoft? There are other keys I want to verify as well.
