I suspect that the problem is deeper than that. Up until a couple of months ago, I had VS2008, 2010, and 2013 on my box, along with SQL Server 2008 and 2012. One day, I decided I'd install VS2015, and didn't use it until about 45 days later, at which time it insisted I couldn't use is, so I got mad and uninstalled it. Then, I installed the BIDS stuff for VS2013, and it insisted on installing SQL Server 2014. I didn't WANT 2014, so I uninstalled it, and then decided that I couldn't use the BIDS stuff, so I uninstalled that. Somewhere deep in the lyrics of the song of my people, I hear the phrase, "your system is hosed up dumbass".
