Hoping someone can help me out. I have a personal copy of Solidworks 2015 Pro I use for contract work at home, and my company just upgraded to 2016. On my computer I have both 2015 and 2016 installed, and can open/edit each respective file type properly. The issue I have is with the WorkGroup PDM Add-In. When I launch Solidworks 2016, the add in loads and I can connect to my office's server with no problems. When I launch 2015, Solidworks seems to try to launch the 2016 add-in rather than the 2015 one. So not surprisingly I cannot connect to my personal server or access any of the files though the add-in. I can however use Solidworks Explorer 2015 to connect to my personal server and do check-out, but obviously cannot take ownership or check anything back in.
Does anyone know how to set-up solidworks 2015 to use the proper add-in? I've tried all the common ideas (Re-installing 2015 & 2016, doing a file->open to the 2015 add-in .dll etc.).
