Hi,We had a situation yesterday in which a member of the DBA team installed SQL 2014 on his [b]Windows-7[/b] desktop and that apparently "corrupted" the earlier-version installs on his machine, so that they became unusable and had to be re-installed.Has anyone had this issue?According to this, there should be no issues with a side-by-side install:[url]http://msdn.microsoft.com/en-us/library/ms143694.aspx[/url]I saw a similar question posted here:[url]http://www.sqlservercentral.com/Forums/Topic1566725-3411-1.aspx[/url]I have seen it suggested in the past that for the purposes of working with new versions of SQL Server it is safer to install those on a dedicated VM, but I don't know how to go about doing that.Any help/thoughts on the above would be appreciated.
