I have SW2013 installed on my machine. A client has SW2010 he does not want me to open up his files in 2013 because he will not be able to open files I have saved files (fair enough) . He has a spare seat of 2010 and has asked if I will work on that on my machine, I do not have a problem in theory as I know you can have more than one version on a PC but what will happen if I have two license? Can I have them both activated in parallel, or will they fight each other?
Thanks for the help,
