We are planning to upgrade from 4.1 sp6 to 4.2 sp6. Developers have 4.1 client tools (BO, CRE, CR13) installed on their machines and currently using it.
How we will be installing 4.2 sp6 tools on developer(s) local machine since they already have 4.1 client tools. I know, laptop or desktop machine cannot have both CR2013 and CR2016 on the same machine.
