How to disable a new version of Solidworks to prevent older version files being overwritten in project?

I have a project which requires me to work on Solidworks 2016. However I have Solidworks 2017 also installed. Is there a way to disable Solidworks 2017 while I am on this project? This will prevent overwriting my Solidworks 2016 files and saving them as the Solidworks 2017 version thus leaving it unusable for the client,
